In the run-up to WWII, many specialized landing craft, both for infantry and vehicles, were developed. At the start of World War II, the Japanese led the world in landing craft design.<ref name="Neushul 1998 133–166">{{Cite journal|last=Neushul|first=Peter|date=1998|title=Andrew Jackson Higgins and the Mass Production of World War II Landing Craft|url=https://www.jstor.org/stable/4233491|journal=Louisiana History: The Journal of the Louisiana Historical Association|volume=39|issue=2|pages=133–166|jstor=4233491|issn=0024-6816}}</ref>

===Specialized infantry landing craft===
[[File:IJA-ship-pioneers-with-Daihatsu-landing-craft.jpg|thumb|In 1941 a Marine Corps officer showed Higgins a picture of the Imperial Japanese Army practicing landings with the Daihatsu landing craft in 1935, a landing craft with a ramp in the bow, and Higgins was asked to incorporate this design into his Eureka boat. He did so, producing the basic design for the Landing Craft, Vehicle, Personnel (LCVP), often simply called the Higgins boat.]]

The [[Daihatsu-class landing craft|Daihatsu-class]] landing craft was lowered to disembark cargo upon riding up onto a beach. After reviewing photos of a Daihatsu landing craft, this was adopted by American landing craft designer [[Andrew Higgins]] in developing the Landing Craft, Personnel (Large) ([[LCP(L)]]) into the Landing Craft, Personnel (Ramped) ([[LCP(R)]]) and later the Landing Craft, Vehicle and Personnel ([[LCVP (United States)|LCVP]]). However, the Daihatsu landing craft was more seaworthy than an LCVP due to its hull design. It was constructed of a metal hull and powered by a [[diesel engine]].

[[Victor H. Krulak|Victor Harold Krulak]], a native of [[Denver]], who joined the [[United States Marine Corps|Marines]] after graduating from [[United States Naval Academy|Annapolis]] in 1934, witnessed the Japanese use small vessels like the ''Daihatsu-class''. In 1937, as a lieutenant in an intelligence outfit during the [[Battle of Shanghai|1937 Battle of Shanghai]], when the Japanese were trying to conquer China, he used a telephoto lens to take pictures of Japanese landing craft with a square bow that became a retractable ramp. Krulak noted that the boats' droppable ramps enabled troops to quickly disembark from the bow, rather than having to clamber over the sides and splash into the surf. Envisioning those ramps as answering the Marines' needs in a looming world war, Lieutenant Krulak showed the photographs to his superiors, who passed on his report to Washington. But two years later, he found that the Navy had simply filed it away with a notation saying it was the work of “some nut out in China.” He persevered, building a balsa wood model of the Japanese boat design and discussing the retractable ramp concept with the [[New Orleans]] boat builder Andrew Higgins. That bow design became the basis for the thousands of Higgins landing craft of World War II.<ref name="Neushul 1998 133–166"/><ref>{{Cite news|last=Goldstein|first=Richard|date=2009-01-05|title=Victor H.

In November 1938, the British [[Inter-Service Training and Development Centre]] proposed a new type of landing craft.<ref name="Maund">Maund, LEH. ''Assault From the Sea'', Methuen & Co. Ltd., London 1949. pp. 3–10</ref> Its specifications were to weigh less than ten [[long ton]]s, to be able to carry the thirty-one men of a British Army [[platoon]] and five [[Royal Engineers|assault engineer]]s or [[Royal Signal Corps|signaller]]s, and to be so shallow drafted as to be able to land them, wet only up to their knees, in eighteen inches of water.<ref name="Maund" /> All of these specifications made the [[Landing Craft Assault]]; a separate set of requirements were laid down for a vehicle and supplies carrier, although previously the two roles had been combined in the [[Motor Landing Craft]].

The [[Landing Craft Assault]] remained the most common British and [[British Commonwealth|Commonwealth]] landing craft of World War II, and the humblest vessel admitted to the books of the [[Royal Navy]] on [[D-Day]]. Prior to July 1942, these craft were referred to as "Assault Landing Craft" (ALC), but "Landing Craft; Assault" (LCA) was used thereafter to conform with the joint US-UK nomenclature system.{{r|Bruce|p=10}}

[[File:Invasion Training in England 02.jpg|thumb|{{USS|LCI-326}}, a [[Landing Craft Infantry]], during training for [[D-Day]]]]

The [[Landing Craft Infantry]] was a stepped up [[amphibious assault ship]], developed in response to a British request for a vessel capable of carrying and landing substantially more troops than the smaller [[Landing Craft Assault]] (LCA). The result was a small steel ship that could land 200 troops, traveling from rear bases on its own bottom at a speed of up to {{convert|15|knots}}. The original British design was envisioned as being a "one time use" vessel which would simply ferry the troops across the [[English Channel]], and were considered an expendable vessel. As such, no troop sleeping accommodations were placed in the original design. This was changed shortly after initial use of these ships, when it was discovered that many missions would require overnight accommodations.

The first LCI(L)s entered service in 1943 chiefly with the Royal Navy (RN) and United States Navy. Some 923 LCI were built in ten American shipyards and 211 provided under lend-lease to the Royal Navy.

===Specialized vehicle landing craft===

Following the [[Inter-Service Training and Development Centre]] 's (ISTDC) successful development of the infantry carrying LCA, attention turned to the means of efficiently delivering a tank to a beach in 1938. Enquiries were made of the army as to the heaviest tank that might be employed in a landing operation. The army wanted to be able to land a 12-ton tank, but the ISTDC, anticipating weight increases in future tank models specified 16 [[95th ton|tons burthen]] for Mechanised Landing Craft designs.<ref name="Maund"/> Another limit on any design was the need to land tanks and other vehicles in less than approximately {{cvt|2+1/2|ft|m|adj=mid|of water}}.<ref>Ladd, 1976, p.42</ref>

Design work began at [[John I. Thornycroft & Company|John I. Thornycroft Ltd.]] in May 1938 with trials completing in February 1940.<ref name="Fergusson"/> Constructed of [[steel]] and selectively clad with armour plate, this shallow-draft, [[barge]]-like boat with a crew of 6, could ferry a tank of 16 long tons to shore at 7 [[knot (unit)|knots]] (13&nbsp;km/h). Depending on the weight of the tank to be transported the craft might be lowered into the water by its davits already loaded or could have the tank placed in it after being lowered into the water.

Although the Royal Navy had the [[LCM 1|Landing Craft Mechanised]] at its disposal, in 1940 Prime Minister [[Winston Churchill]] demanded an amphibious vessel capable of landing at least three 36-ton [[heavy tank]]s directly onto a beach, able to sustain itself at sea for at least a week, and inexpensive and easy to build. [[Loben Edward Harold Maund|Admiral Maund]], Director of the Inter-Service Training and Development Centre (which had developed the Landing Craft Assault<ref name="globalsecurity">{{cite web|url=http://www.globalsecurity.org/military/systems/ship/lct.htm|title=Landing Craft, Tank (LCT)|work=globalsecurity.org|access-date=17 January 2011}}</ref>), gave the job to naval architect Sir Roland Baker, who within three days completed initial drawings for a {{Convert|152|ft|m|adj=on}} landing craft with a {{Convert|29|ft|m|adj=on}} beam and a shallow draft. Ship builders [[Fairfield Shipbuilding and Engineering Company|Fairfields]] and [[John Brown & Company|John Brown]] agreed to work out details for the design under the guidance of the Admiralty Experimental Works at [[Haslar]]. Tank tests with models soon determined the characteristics of the craft, indicating that it would make {{Convert|10|kn}} on engines delivering about {{Convert|700|hp|abbr=on}}.<ref name="tinarmada">{{cite web|url=http://ww2lct.org/history/stories/tin_armada.htm |title=The Tin Armada: Saga of the LCT |author=Basil Hearde |work=ww2lct.org |access-date=15 January 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110902182446/http://ww2lct.org/history/stories/tin_armada.htm |archive-date= 2 September 2011 }}</ref> Designated the LCT Mark 1, 20 were ordered in July 1940 and a further 10 in October 1940.<ref name="globalsecurity"/>

The first LCT Mark 1 was launched by [[Hawthorn Leslie and Company|Hawthorn Leslie]] in November 1940. It was an all-welded 372-ton steel-hulled vessel that drew only {{Convert|3|ft}} of water at the bow. Sea trials soon proved the Mark 1 to be difficult to handle and almost unmanageable in some sea conditions. The designers set about correcting the faults of the Mark 1 in the LCT Mark 2. It was longer and wider, with {{convert|15|and|20|lb|adj=on}} armoured shielding added to the wheelhouse and gun tubs.

[[File:LCT202.jpg|thumb|right|LCT-202 off the coast of England, 1944]]

The Mark 3 had an additional {{Convert|32|ft|adj=on}} midsection that gave it a length of {{Convert|192|ft}} and a displacement of 640 tons. Even with this extra weight, the vessel was slightly faster than the Mark 1. The Mk.3 was accepted on 8 April 1941. The Mark 4 was slightly shorter and lighter than the Mk.3, but had a much wider beam ({{Convert|38|ft|9|in|m|abbr=on}}) and was intended for cross channel operations as opposed to seagoing use. When tested in early assault operations, like the ill-fated Allied [[Dieppe Raid|raid on Dieppe]] in 1942, the lack of manoeuvring ability led to the preference for a shorter overall length in future variants, most of which were built in the United States.

When the United States entered the war in December 1941, the U.S. Navy had no amphibious vessels at all, and found itself obliged to consider British designs already in existence. One of these, advanced by K.C. Barnaby of [[John I. Thornycroft & Company|Thornycroft]], was for a double-ended LCT to work with landing ships. The [[Bureau of Ships]] quickly set about drawing up plans for landing craft based on Barnaby's suggestions, although with only one ramp. The result, in early 1942, was the LCT Mark 5, a {{convert|117|ft|adj=on}} craft that could accommodate five 30-ton or four 40-ton tanks or 150 tons of cargo. This 286-ton landing craft could be shipped to combat areas in three separate water-tight sections aboard a cargo ship or carried pre-assembled on the flat deck of a [[Landing Ship, Tank]] (LST). The Mk.5 would be launched by heeling the LST on its beam to let the craft slide off its chocks into the sea, or cargo ships could lower each of the three sections into the sea where they were joined together.<ref name="tinarmada"/>

===Development of Landing Ships===
Due to their small size, most amphibious ships and craft were not given names and were just given serial numbers, e.g., ''LCT 304''. The LSTs and LSDs were an exception to this, since they were similar in size to a small [[cruiser]]. In addition, three British-built LSTs were named: {{HMS|Boxer|F121|6}}, {{HMS|Bruiser|F127|6}} and {{HMS|Thruster|F131|6}}; these were all larger than the U.S. design and had proper funnels.

====Landing Ship, Tank====
[[Image:LST Sicily.jpg|thumb|left|upright|A [[Canada|Canadian]] LST off-loads an [[M4 Sherman]] during the [[Allied invasion of Sicily]] in 1943.]]
A further development was the [[Landing Ship, Tank]] designation, built to support amphibious operations by carrying significant quantities of vehicles, cargo, and [[landing troops]] directly onto an unimproved shore. The British [[Operation Dynamo|evacuation from Dunkirk]] in 1940 demonstrated to the [[British Admiralty|Admiralty]] that the Allies needed relatively large, ocean-going ships capable of shore-to-shore delivery of [[tank]]s and other vehicles in amphibious assaults upon the continent of Europe. The first purpose-built LST design was {{HMS|Boxer|F121|6}}. To carry 13 [[Churchill tank|Churchill]] [[infantry tank]]s, 27 vehicles and nearly 200 men (in addition to the crew) at a speed of 18 knots, it could not have the shallow draught that would have made for easy unloading. As a result, each of the three (''Boxer'', ''Bruiser'', and ''Thruster'') ordered in March 1941 had a very long ramp stowed behind the bow doors.

In November 1941, a small delegation from the British Admiralty arrived in the United States to pool ideas with the [[United States Navy]]'s [[Bureau of Ships]] with regard to development of ships and also including the possibility of building further ''Boxer''s in the US.<ref>Brown, D.K. (Ed.), ''The Design And Construction Of British Warships 1939–1945'', Vol 3 Amphibious Warfare Vessels And Auxiliaries. {{ISBN|0-85177-675-2}}, p.143</ref> During this meeting, it was decided that the Bureau of Ships would design these vessels. The LST(2) design incorporated elements of the first British LCTs from their designer, Sir Rowland Baker, who was part of the British delegation. This included sufficient buoyancy in the ships' sidewalls that they would float even with the tank deck flooded.<ref>Brown, D.K. p.143</ref> The LST(2) gave up the speed of HMS ''Boxer'' at only 10 knots but had a similar load while drawing only 3 feet forward when beaching.

Congress provided the authority for the construction of LSTs along with a host of other auxiliaries, [[destroyer escort]]s, and assorted landing craft. The enormous building program quickly gathered momentum. Such a high priority was assigned to the construction of LSTs that the previously laid keel of an [[aircraft carrier]] was hastily removed to make room for several LSTs to be built in her place. The keel of the first LST was laid down on 10 June 1942 at [[Newport News, Virginia|Newport News]], Va., and the first standardized LSTs were floated out of their building dock in October. Twenty-three were in commission by the end of 1942. Lightly armored, they could steam cross the ocean with a full load on their own power, carrying infantry, tanks and supplies directly onto the beaches. Together with 2,000 other landing craft, the LSTs gave the troops a protected, quick way to make combat landings, beginning in summer 1943.<ref>Isely and Crowl, ''The U.S. Marines and Amphibious War Its Theory and Its Practice in the Pacific'' (1951)  ch 3 {{page needed|date=June 2014}}</ref>

====Landing Ship, Dock====
[[File:AAVs preparing to debark USS Gunston Hall (LSD 44).jpg|thumb|left|[[Amphibious vehicle]]s inside a US LSD]]

The ''[[Dock Landing Ship|''Landing Ship Dock'']]'' (LSD) came as a result of a British requirement for a vessel that could carry large landing craft across the seas at speed. The first LSD came from a design by Sir Roland Baker and was an answer to the problem of launching small craft rapidly. The "Landing Ship Stern Chute", which was a converted train ferry, was an early attempt. Thirteen [[Landing Craft Mechanized]] (LCM) could be launched from these ships down the chute. The Landing Ship Gantry was a converted tanker with a crane to transfer its cargo of landing craft from deck to sea—15 LCMs in a little over half an hour.

The design was developed and built in the US for the USN and the [[Royal Navy]]. The LSD could carry 36 LCM at 16 knots. It had a large open compartment at the back. Opening a [[stern]] door and flooding special compartments opened this area to the sea so that LCI-sized vessels could enter or leave. It took one and a half hours for the dock to be flooded down and two and half to pump it out. When flooded they could also be used as docks for repairs to small craft.

====Landing Craft Navigation (LCN)====
Nine-ton ''Landing Craft Navigation (LCN)'' were used by British "Combined Operations Assault Pilotage Parties" ([[Royal Marine]] and [[Special Boat Service]] crew) for surveying landing sites.<ref>{{cite web|url=http://www.combinedops.com/COPPs.htm |title=Accessed 18 March 2008 |publisher=Combinedops.com |date=1943-03-09 |access-date=2009-05-10}}</ref>

====Landing Craft Control (LCC)====
The ''Landing Craft Control (LCC)'' were {{convert|56|ft|m|0|adj=on}} [[United States Navy|U.S. Navy]] vessels, carrying only the crew ([[Scouts and Raiders]]) and newly developed radar. Their main job was to find and follow the safe routes in to the beach, which were lanes that had been cleared of obstacles and mines. There were eight in the entire Normandy invasion (two per beach).{{citation needed|date=May 2014|reason=There were 5 beaches - either there were 10, or not every beach had 2!}} After leading in the first wave, they were to head back out and bring in the second wave. After that, they were used as all-purpose command and control assets during the invasion.

====Amphibious vehicles====
Very small landing craft, or amphibians, were designed. The [[United States|U.S.]]-designed ''[[Landing Vehicle Tracked]]'', was an amphibious (and sometimes armored) personnel carrier. These were operated by Army personnel, not naval crews and had a capacity of about three tons. The British introduced their own amphibian, the [[Terrapin (amphibious vehicle)|''Terrapin'']].

===Fire support craft===
It was soon realized that [[battleship]]s, [[cruiser]]s and [[destroyer]]s could not necessarily provide all the [[fire support]] (including [[suppressive fire]]) that an amphibious assault might need.{{citation needed|date=June 2014}} Therefore, specialized vessels were developed that incorporated various direct and indirect fire weapons. These included guns and rockets which could be mounted on landing craft and landing ships. As part of the final barrage before an assault, the landing area would be plastered by these types.

Amphibious landing craft of WWII were generally fitted out with minimal weaponry. [[Landing Craft Assault|LCA]] crews were issued with .303 inch [[Lewis Gun]]s, which were mounted in a light machine gun shelter on the forward-port side of the craft; these could be used both as anti-aircraft protection and against shore targets. Later models were fitted with two [[2-inch mortar]]s, and two Lewis or .303 [[Bren light machine gun]]s. LCM 1 crews were issued with Lewis guns, and many LCM 3s had .50 in (12.7&nbsp;mm) Browning machine guns mounted for anti-aircraft protection.<ref>US Navy ONI 226 Allied Landing Craft and Ships, US Government Printing Office, 1944.{{page needed|date=June 2014}}</ref> Opportunities for troops on board to use their own weapons presented themselves.

LCIs and LCTs carried heavier weapons, such as the [[Oerlikon 20 mm cannon]], on each side of the bridge structure. LSTs had a somewhat heavier armament.

Some landing craft were converted for special purposes either to provide defence for the other landing craft in the attack or as support weapons during the landing.

====Landing Craft Assault (Hedgerow)====
The LCA(HR) was a converted British LCA. It carried a battery of 24 [[spigot mortar]]s, the Royal Navy's [[Hedgehog (weapon)|Hedgehog anti-submarine weapon]], instead of personnel. The mortars were fired as a barrage onto the beach to clear mines and other obstructions. Having discharged its mortars and its duty, the LCA(HR) would leave the beach area. They were towed to the beach by larger craft, such as the LCTs that carried the [[Royal Engineer]] assault teams with their [[Hobart's Funnies|specialist vehicles and equipment]], who would complete the beach clearance.

Three flotillas (of 18, 18 and 9 craft) were used at Juno, Gold and Sword beaches.<ref>{{cite web |url=http://www.royalmarinesmuseum.co.uk/item/researching-family-and-royal-marine-history/major-landing-craft-of-world-war-ii |title=Major Landing Craft of World War II |date=6 October 2011 |publisher=The Royal Marines Museum |access-date=7 October 2011 |archive-url=https://web.archive.org/web/20140609011918/http://www.royalmarinesmuseum.co.uk/item/researching-family-and-royal-marine-history/major-landing-craft-of-world-war-ii |archive-date=9 June 2014 |url-status=dead }}</ref>

====Landing Craft Flak====
[[File:Lcf (4) 24 FL5979.jpg|thumb|Landing Craft Flak were equipped with [[Oerlikon 20 mm cannon|20 mm Oerlikons]] and four [[QF 2 pounder naval gun|QF 2 pdr "pom-poms"]] to defend against aircraft.]]
The Landing Craft Flak (LCF) was a conversion of the LCT that was intended to give [[anti-aircraft]] support to the landing. They were first used in the [[Dieppe Raid]] early in 1942. The ramp was welded shut, and a deck built on top of the Tank deck. They were equipped with several light anti-aircraft guns—a typical fitting was eight [[Oerlikon 20 mm cannon|20 mm Oerlikons]] and four [[QF 2 pounder naval gun|QF 2 pdr "pom-poms"]] and had a crew of 60. On British examples, the operation of the craft was the responsibility of RN crew and the guns were manned by [[Royal Marines]]. They carried two naval officers and two marine officers.

====Landing Craft Gun====
[[File:Lcg (l) 680 FL5995.jpg|thumb|Landing Craft Gun (Large) 680 carried two 4.7-inch naval guns]]
 
The [[Landing Craft Gun]] (LCG) was another LCT conversion intended to give supporting fire to the landing. Apart from the Oerlikon armament of a normal LCT, each LCG(Medium) had two British Army [[Ordnance 25 pounder|25 pounder gun-howitzers]] in armoured mountings, while LCG(L)3 and LCG(L)4 both had two [[4.7 inch gun|4.7-inch naval guns]] ({{cvt|4.7|in|cm|disp=out}}).<ref>Brown, D K. ''Nelson to Vanguard''. p. 145.</ref> Crewing was similar to the LCF. LCGs played a very important part in the [[Battle of the Scheldt|Walcheren operations]] in October 1944.

====Landing Craft Rocket====
[[File:LCT(R) 459.png|thumb|300px|LCT (R) 459]]

The [[Landing craft tank (rocket)|Landing Craft Tank (Rocket)]], LCT(R), was an LCT modified to carry a large set of launchers for the British [[RP-3]] "60&nbsp;lb" rockets mounted on the covered-over tank deck. The full set of launchers was "in excess of" 1,000 and 5,000 reloads were kept below. The firepower was claimed to be equivalent to 80 [[light cruiser]]s or 200 destroyers.

The method of operation was to anchor off the target beach, pointing towards the shore. The distance to the shore was then measured by [[radar]] and the elevation of the launchers set accordingly. The crew then vanished below (apart from the commanding officer who retreated to a special cubby hole to control things) and the launch was then set off electrically. The launch could comprise the entire set or individual ranks of rockets.<ref>[http://www.navyhistory.org.au/british-landing-craft-of-world-war-ii/ British Landing Craft of World War II]  Naval Historical Society<!-- Bot generated title --></ref>

A full reload was a very labor-intensive operation and at least one LCT(R) went alongside a cruiser and got a working party from the larger ship to assist in the process.

====Landing Craft Support====
[[File:The Royal Navy during the Second World War A28452.jpg|thumb|right|{{center|Royal Marines of Force T manning an LCS (M) in South West Holland}}]] 
[[File:Lcs (l) 256 FL5827.jpg|thumb|Landing Craft Support (Large) was armed with an anti-tank gun in a turret.]]
The Landing Craft Support was used to give some firepower close in.

The Landing Craft Support (Medium) (LCS(M)), Mark 2 and Mark 3 were used by the British forces at Normandy. The crew was Royal Navy, with Royal Marines to operate the weapons: two 0.5&nbsp;inch [[Vickers machine gun]]s and a 4-inch mortar to fire smoke shells.

The [[Fairmile H landing craft|Fairmile H Landing Craft]] Support (Large) had armour added to its wooden hull and a turret with an anti-tank gun fitted. The LCS(L) Mark 1 had a [[Daimler armoured car]] turret with its [[Ordnance QF 2 pounder|QF 2–pdr]] (40&nbsp;mm) gun. The Mark 2 had a [[Ordnance QF 6 pounder|QF 6–pdr]] (57&nbsp;mm) anti–tank gun.

The American [[Landing Craft Support]] was larger, each was armed with a 3-inch gun ({{cvt|3|in|cm|disp=out}}), various smaller guns, and ten MK7 rocket launchers.

===Inflatable landing craft===
[[Inflatable boat]]s were often used to transport amphibious troops from [[high speed transport]]s and submarines. The United States used a 7-man Landing Craft, Rubber (Small) ([[LCRS|LCR-S]]) and a 10-man Landing Craft, Rubber (Large) ([[LCRL|LCR-L]]<ref>{{cite web|url=http://www.ibiblio.org/hyperwar/USN/ships/ships-slc.html |title=US Navy Small Landing Craft, 1940–1945 |publisher=Ibiblio.org |date=2006-05-25 |access-date=2009-05-10}}</ref>).

The first and last instances of the large use of rubber boats in amphibious operations in World War II were the [[Makin Island raid]] in 1942 and the landing of the [[1st Battalion 6th Marines]] [[Battle of Tarawa#November 22|Battle of Tarawa]] in 1943 where the Battalion commander Major [[William K. Jones]] was nicknamed "Admiral of the Condom Fleet".<ref>p. 46 Jablon, Howard ''David M. Shoup: A Warrior Against War''

===Landing Craft Group and wartime training===

After Pearl Harbor, the U.S. Army and Navy began intense planning for the transport of millions of men into combat and the training for amphibious operations. By June 1942, Amphibious Force, Atlantic Fleet (AFAF) established headquarters at Norfolk (Virginia) under the command of [[Henry Kent Hewitt|Admiral Henry Kent Hewitt]]. Temporary headquarters for a transport command were set up in an old [[American Export-Isbrandtsen Lines#American Export Lines .28I.29|American Export Line]] transport ship that had been built for the Army in World War I.<ref name="Burton, By Sea and By Land">{{cite book|last1=Burton|first1=Lt.

Clarke]] began at the end of June 1942," according to Naval historian Samuel Eliot Morison.<ref name="Morison, Operations in North African Waters">{{cite book|last1=Morison|first1=Samuel Eliot|title=History of United States Naval Operations in World War II, Vol. II: Operations in North African Waters, October 1942-June 1943|date=1957|publisher=Little, Brown and Company|location=Boston|isbn=1591145481|page=28|url=https://books.google.com/books?id=QnG9XrKQTgoC&pg=PA28}}</ref> Clarke was given orders to "secure, organize, and train crews for approximately 1,800 landing craft" including [[Landing Ship, Tank|LST]]s and [[Landing Craft Infantry|LCI]]s, which at that time were still in the design phase.<ref name="Burton, By Sea and By Land"/>{{Rp|70}}

To man and support such landing craft, the Navy ordered that 30,000 men and 3,000 officers be trained in a matter of months, but initially the Landing Craft Group consisted only of Capt. Clarke, two officers and a yeoman. In creating training programs, Clarke studied blueprints for the new craft and "from these paper drawings he prepared ship's organizations for each type. This was the first textbook for crews assigned to the large landing craft. From this, they were to be trained in what their duties were to be, what the ship would be like, and how it would be expected to operate."<ref name="Burton, By Sea and By Land"/>{{Rp|67}}

In August 1942, Capt. Clarke was told about [[Operation Torch]] and secret plans to invade North Africa the following November. He had only a few months to train thousands of men, most of whom were just out of indoctrination school. "They were the butchers, the bakers, and the light bulb makers of American youth. War was new to them, and organized Navy life was strange," observed Lt. Eric Burton, a Naval officer who wrote ''By Sea and by Land'', a semi-official account published during the War about amphibious combat.<ref name="Burton, By Sea and By Land"/>

Capt. Clarke created hydrographic, maintenance, medical, and communications training programs, and a section to train Army shore parties how to unload landing craft. He set up a training facility at [[Solomons, Maryland|Solomons Island]], and held exercises on the shores of the Chesapeake Bay around the clock, day and night.

On 1 September 1942, the Amphibious Force and its Landing Craft Group rented the Nansemond Hotel, a popular resort hotel on Virginia Beach near Norfolk, to use as a headquarters building. Eventually, 40 major amphibious operations would be planned at the old hotel. For several weeks, [[George S. Patton|Gen. George S. Patton]] worked on plans for the invasion of North Africa out of the Nansemond.<ref>{{cite web|title=Old Nansemond Hotel, Ocean View Norfolk, Virginia|url=http://wikimapia.org/28099113/Old-Nansemond-Hotel-Ocean-View-Norfolk-Virginia|website=Wikimapia|access-date=29 July 2015}}</ref>

"Captain Clarke had less than two months, about one-third of what had been considered the minimum, to train these men to conduct night ship-to-shore landings," wrote Samuel Eliot Morison about the preparations for Operation Torch. "Considering the time limitations, his performance was remarkable."<ref name="Morison, Operations in North African Waters" /> Clarke was awarded the [[Legion of Merit]] for the accomplishment. According to the Presidential citation, he and the Landing Craft Group "brought these ships and craft to a high state of readiness for combat operations in all subsequent major amphibious operations in the Atlantic, Pacific, and Mediterranean theatres.<ref name="Clarke Legion of Merit citation, March, 1945">{{cite journal|title=William Price Oliver Clarke|url=http://valor.militarytimes.com/recipient.php?recipientid=311355 |publisher=Bureau of Naval Personnel |journal=Information Bulletin |issue=336 |date=March 1945}}</ref>
