'''Daniel Judson Callaghan''' (July 26, 1890&nbsp;– November 13, 1942) was a [[United States Navy]] officer who served his country in two wars, in a three-decades-long career. Callaghan served on several ships during his first 20 years of service, including escort duties during [[World War I]], and also filled some shore-based administrative roles. He later came to the attention of President [[Franklin D. Roosevelt]], who appointed Callaghan as his naval aide in 1938.<ref name="SaintIgnatius2005">{{Cite web|access-date=September 8, 2009 |url=http://www.siprep.org/genesis/documents/Genesis05Spring.pdf |work=History Supplement: Admiral Daniel Callaghan (SI 1907) |title=Genesis IV: The Alumni Magazine of Saint Ignatius College Preparatory |year=2005 |pages=32–34 |url-status=dead |archive-url=https://web.archive.org/web/20100613050907/http://siprep.org/genesis/documents/Genesis05Spring.pdf |archive-date=June 13, 2010 }}</ref> A few years later, he returned to command duties during the early stages of [[World War II]]. At the [[Naval Battle of Guadalcanal]], during a surface action against a larger [[Imperial Japanese Navy|Japanese]] force off [[Savo Island]], an enemy shell killed Callaghan on the bridge of his [[flagship]], {{USS|San Francisco|CA-38|6}}. Callaghan received the [[Medal of Honor]] posthumously for his actions. He was the third of five US Navy admirals [[List of U.S. general officers and flag officers killed in World War II|killed in battle during WWII]], including: [[Isaac C. Kidd]] (1941, [[Attack on Pearl Harbor]]); [[Norman Scott (admiral)|Norman Scott]] (earlier on same night, in same battle, as Callaghan); [[Henry M.

==Early life==
Callaghan was born on July 26, 1890, in San Francisco, California, the son of businessman Charles William Callaghan and Rose Wheeler Callaghan.<ref name="Murphy1954a">{{cite book |last=Murphy |first=F.

Callaghan|William Callaghan]] (1897–1991), would later go on to a career in the US Navy as well. Both brothers studied at [[St. Ignatius College Preparatory|Saint Ignatius College Preparatory]] in San Francisco, the elder graduating in the class of 1907.<ref name="SaintIgnatius2005"/> He then graduated from the [[United States Naval Academy]] in 1911.<ref name="SaintIgnatius2005"/><ref name=starr>{{Cite book|last=Starr|first=Kevin|url=https://www.worldcat.org/oclc/59360288|title=California: a history|date=2005|publisher=Modern Library|isbn=0-679-64240-4|edition=1st|location=New York|oclc=59360288}}</ref> His first assignment was on board the [[armored cruiser]] {{USS|California|ACR-6|6}}, in command of a [[Gun turret|turret]] with twin {{convert|8|in|adj=on|0}} guns.

[[File:USSTruxtunDD14.jpg|thumb|left|USS ''Truxtun'' was Callaghan's second posting, and later became his first command|alt=A black and white image of the Truxtun in open water.]]

His second assignment was on the [[destroyer]] {{USS|Truxtun|DD-14|6}} in mid-1913. He was promoted to [[lieutenant (junior grade)]] in May 1915.<ref name="Murphy1954c"/> In his first few years of service, he developed a reputation as a conscientious sailor, noted for avoiding heavy alcohol consumption and regularly attending [[Mass (liturgy)|Mass]]. His dedication to [[Naval artillery|naval gunnery]] also became apparent. Some years later, one of his captains, Joel Pringle, would write: "[Callaghan's] devotion to duty, sound judgment and ability to inspire loyalty in his subordinates have resulted in a constant and steady increase in the efficiency of the above mentioned batteries. At the recent battle practice of the Pacific Fleet in 5-inch guns, he made the largest percentage of hits of any ship of the Fleet."<ref name="Murphy1954d">{{cite book |last=Murphy |first=F.

During his first few years of naval service, Callaghan had been courting Mary Tormey of [[Oakland, California]]; the two married on July 23, 1914.<ref name="Murphy1954c"/> Their son, Daniel Judson Callaghan Jr.,<ref name="Murphy1954d"/><ref name="Time1942">{{cite magazine |access-date=September 12, 2009 |url=http://www.time.com/time/magazine/article/0,9171,886051,00.html |archive-url=https://web.archive.org/web/20081204230853/http://www.time.com/time/magazine/article/0,9171,886051,00.html |url-status=dead |archive-date=December 4, 2008 |title=Army & Navy – Medals: Signs of action |magazine=[[Time (magazine)|Time]] |date=December 21, 1942}}</ref> was born in [[Alameda, California]], on October 16, 1915.<ref name="CB">{{Cite web |access-date=November 13, 2009 |url=http://www.familytreelegends.com/records/calbirths?c=search&first=Daniel&last=Callaghan&spelling=Exact&4_year=&4_month=0&4_day=0&5=&7=&SubmitSearch.x=49&SubmitSearch.y=21&SubmitSearch=Submit |title=California Births 1905–1995}}</ref>

In July 1915, ''Truxtun'' was on its way to Alaska when it broke down and could not continue its mission. Initially, the blame fell on Callaghan, who had apparently ordered incorrect condenser parts. He was suspended from duty and ordered to appear before a [[court-martial]].<ref name="Murphy1954c"/> Subsequent investigation, however, found that another man was responsible for the error, and Callaghan received a full acquittal and was reinstated. A few months later, he was appointed as commanding officer of ''Truxtun'', but the stress of his trial appeared to have left its mark—at the age of 25 years, his hair had already turned gray.<ref name="Murphy1954c"/>

==World War I==
Callaghan's next posting was to the cruiser {{USS|New Orleans|CL-22|6}} in November 1916.<ref name="Murphy1954d"/> Following the entry of the United States into World War I, in April 1917, ''New Orleans'' escorted cargo ships crossing the Atlantic Ocean. At this time, he first met Ross McIntire, a surgeon, who would later have a significant impact on his career. According to biographer Francis Murphy, Callaghan played a pivotal role in the rescue of a disabled British [[ocean liner]] off the coast of Ireland: "Four times a hawser was hauled aboard the cruiser from the liner, that was about three times the cruiser's size, and four times the cable parted. The Captain was for abandoning the job. But not Dan. With superhuman strength and the full cooperation of his men, he finally secured the cable. For forty-eight hours the ''New Orleans'' stayed with the stricken vessel hauling it out of danger [and] finally handing it on to tugs from a North Ireland base."<ref name="Murphy1954d"/>

[[File:USS Idaho (BB-42) USS Texas (BB-35) - NH 73834.jpg|thumb|left|upright|USS ''Idaho'' during battle practice around 1930|alt=A black and white image of the Idaho in open water.]]

Following the war, he settled in [[Georgetown, Washington, D.C.]] for two years with his wife and young son. During this time, he worked on the reassignment of [[Warrant officer|warrant]] and [[chief petty officer]]s from the navy.<ref name="Murphy1954d"/> Callaghan next served aboard the newly commissioned [[battleship]] {{USS|Idaho|BB-42|6}}, commencing in October 1920.<ref name="Murphy1954d"/> While his family moved back to Oakland, he began serving as a fire control officer on ''Idaho''. He left ''Idaho'' in June 1923, returning to shore duties for two years before taking up the position of first lieutenant on the battleship {{USS|Colorado|BB-45|6}} in May 1925.<ref name="Murphy1954d"/> ''Colorado'' transported a shipment of gold to Australia before returning to the United States in 1926. His next assignment was the position of gunnery officer on board the battleship {{USS|Mississippi|BB-41|6}}.<ref name="Murphy1954d"/> Captain Thomas Hart wrote of Callaghan: "I can scarcely report too favorably on this officer. He is excellent generally and particularly; and he looks and acts the part. As gunnery officer, he is being highly successful and I unhesitatingly recommend him for almost any detail."<ref name="Murphy1954d"/>

Callaghan left ''Mississippi'' in July 1928 and worked in naval inspections for the next two years. He served as aide to the commander in chief, US Fleet, and was promoted to the rank of [[Commander (United States)|commander]] in June 1931.<ref name="NHC">{{Cite web |access-date=September 12, 2009 |url=http://www.history.navy.mil/photos/pers-us/uspers-c/d-calgn.htm |publisher=[[Naval Historical Center]] |title=Rear Admiral Daniel J.

==World War II==
In May 1941, during the early stages of World War II, Roosevelt released Callaghan to take command of the cruiser {{USS|San Francisco|CA-38|6}}.<ref name="SaintIgnatius2005"/><ref name="NHC"/> Roosevelt wrote: "It is with great regret that I am letting Captain Callaghan leave as my Naval Aide. He has given every satisfaction and has performed duties of many varieties with tact and real efficiency. He has shown a real understanding of the many problems of the service within itself and in relationship to the rest of Government."<ref name="SaintIgnatius2005"/>

In April 1942, he was promoted to the rank of [[Rear admiral (United States)|rear admiral]] and was appointed as chief of staff to the commander, South Pacific Area and South Pacific Force Vice Admiral [[Robert L. Ghormley]].<ref name="NHC"/> He served in that billet until Vice Admiral Ghormley was relieved on 18 October 1942. 

===Naval Battle of Guadalcanal===
As commander of Task Group 67.4,<ref>{{Cite web|url=http://taskforce67.tripod.com/tf67.htm|title = Commander Amphibious Force TF-64}}</ref> he commanded U.S. naval forces against Japanese warships during the [[Naval Battle of Guadalcanal#First Naval Battle of Guadalcanal, 13 November|First Naval Battle of Guadalcanal]] on 13 November 1942.<ref name=starr/>  He was on the bridge of the USS ''San Francisco'' when enemy fire killed him and most of his command staff.<ref name=starr/><ref name="NHC"/> At that time, he became [[List of U.S. general officers and flag officers killed in World War II|the third US Navy admiral killed in action during World War II]].{{Ref_label|A|a|none}}

Following his death, [[Lieutenant Commander]] [[Bruce McCandless]] assumed operational command of ''San Francisco''.<ref name="Pearson1942">{{Cite news |access-date=September 11, 2009 |author=Pearson, Drew |orig-year=1942 |url=https://news.google.com/newspapers?nid=888&dat=19421226&id=9bQKAAAAIBAJ&sjid=dk0DAAAAIBAJ&pg=7128,783939 |title=Naval hero feared court-martial but got Congressional medal |work=[[Saint Petersburg Times]] |date=December 26, 1942}}</ref>{{Ref_label|B|b|none}} Earlier in the battle, Rear Admiral [[Norman Scott (admiral)|Norman Scott]] had been killed, so two US commanders had now been lost, as well as several of their staff. Despite the deaths of so many senior officers, the battle ended in a strategic victory for the [[Allies of World War II|Allied]] side.<ref name="Time1942"/>

In hindsight, Callaghan was criticized for not distributing his five ships that had the superior [[SG radar]] systems throughout his battle line, for not using one of them as his flagship, for directing the battle from his flagship's bridge instead of the radar plot, for not issuing his battle plans to his captains, and for giving confusing orders during the battle. Analysis of the battle led to a rapid improvement in USN techniques for fighting in poor visibility, particularly in adopting [[combat information center]]s.<ref>{{cite book | last = Hammel | first = Eric | author-link = Eric M.

Callaghan was buried at sea. He was survived by his wife, Mary Tormey Callaghan,<ref name="SaintIgnatius2005"/> and son, Daniel Judson Callaghan Jr.<ref name="Time1942"/> (1915–2006). By order of President Roosevelt, both Rear Admirals Callaghan and Scott were posthumously awarded the [[Medal of Honor]].

===Medal of Honor===
Callaghan's Medal of Honor citation read:
<blockquote>For extraordinary heroism and conspicuous intrepidity above and beyond the call of duty during action against enemy Japanese forces off Savo Island on the night of 12–13 November 1942. Although out-balanced in strength and numbers by a desperate and determined enemy, Rear Admiral Callaghan, with ingenious tactical skill and superb coordination of the units under his command, led his forces into battle against tremendous odds, thereby contributing decisively to the rout of a powerful invasion fleet and to the consequent frustration of a formidable Japanese offensive. While faithfully directing close-range operations in the face of furious bombardment by superior enemy fire power, he was killed on the bridge of his Flagship. His courageous initiative, inspiring leadership, and judicious foresight in a crisis of grave responsibility were in keeping with the finest traditions of the United States Naval Service. He gallantly gave his life in the defense of his country.<ref name="NHC"/></blockquote>
His son was a [[lieutenant (junior grade)]] at the time and accepted his father's Medal of Honor on his behalf.<ref name="Time1942"/>

'''a.''' {{note_label|A|a|none}} The first two US Navy admirals killed in action during World War II were fellow Rear Admirals Norman Scott, earlier in the same engagement, and [[Isaac C. Kidd|Isaac Kidd]], killed on the bridge of USS ''Arizona'' at Pearl Harbor.

'''b.''' {{note_label|B|b|none}} While this would normally have been grave misconduct, McCandless reportedly did so because: (1) he was intimately familiar with the plan of attack and was afraid that there would be mistakes if command passed on to another ship, and (2) he wanted to prevent news of Callaghan's death reaching the enemy (through radio interception). McCandless received the Medal of Honor for his action.<ref name="Pearson1942"/>
