Editing HMS E11 (section)

===European operations===
''E11'' joined the [[8th Submarine Flotilla]] at [[Harwich]] following [[sea trials]] on 2 October 1914 under the command of [[Lieutenant-Commander]] [[Martin Dunbar-Nasmith|Martin Nasmith]].<ref>Harris, p. 325</ref><ref>He would go on to command [[Anti-submarine warfare|A/S]] forces in [[Western Approaches]] during the [[Second World War]].</ref>

Later that month, on her first war patrol ''E11'' was dispatched to the [[Baltic Sea]] along with two other submarines. Nasmith was deterred from breaking through the entrance to the Baltic by numerous vessels and warships in Swedish waters during a night passage. Next morning he mistook {{ship|HDMS|Havmanden|A 3|2}}, a submarine of [[Neutral country|neutral]] [[Denmark]], for the German submarine {{SMS|U-3|Germany|6|sub=y}}. The misidentification was principally caused by the pennant number "3" on her [[conning tower]]. Two [[torpedo|torpedoes]] were fired, one of which glanced off the bottom of the hull, causing no damage and a minor diplomatic incident.<ref>Harris, pp. 190–198</ref><ref>{{cite book | last = Compton-Hall | first = Richard | title = Submarines at War, 1914–18 | location = [[Penzance]] | publisher= Periscope Publishing | year = 2004 | orig-year = 1991 | isbn = 978-1-904381-21-1 | oclc = 57639764 | page = 140 }}</ref> ''E11'' then returned to Harwich.

During the [[Scarborough Raid]] in December 1914, ''E11'' was sent into the [[Heligoland Bight]] to intercept the returning German Fleet. However, it had already returned to harbour by the time ''E11'' arrived. On the following morning Nasmith was able to attack the [[battleship|battleships]] of the [[I Battle Squadron|1.Geschwader]] in transit from the [[Elbe]] to the [[Jade (river)|Jade]]. His torpedo missed the leading battleship, [[SMS Ostfriesland|SMS ''Ostfriesland'']], which was unaware of the attack.<ref>Harris, pp. 278–283</ref><ref>A number of sources record the vessel attacked as [[SMS Posen|SMS ''Posen'']], the fifth vessel in the squadron. ''Posen'' actually sighted ''E11'' some time after the torpedo was fired when ''E11'' lost control during a second abandoned attack and broke surface.</ref>

''E11'' took part in the [[Cuxhaven Raid]], which culminated on 25 December 1914 in the attack by seven [[seaplane|seaplanes]] from the [[seaplane carrier|seaplane carriers]] {{HMS|Engadine|1911|6}}, {{HMS|Riviera}}, and {{HMS|Empress|1914|6}} (escorted by three [[cruiser]]s and several [[destroyer]]s of the [[Harwich Force]]) on [[Zeppelin]] sheds and other military targets near [[Cuxhaven]]. Four of the aircraft failed to regain their ships. ''E11'' was acting as a mark boat on their return route. Three aircraft which were running out of fuel saw ''E11'' and alighted nearby. The five aircrew were rescued by ''E11'' whilst Zeppelin [[List of Zeppelins|''L 5 (LZ 28)'']] closed to attack. Two bombs were dropped and exploded nearby as ''E11'' submerged. Nasmith received a mention in despatches.<ref>Harris, pp. 301–308</ref><ref>Barnes & James, p.98.</ref><ref>The rescued pilots were Flight Lieutenant Arnold John Miley (aircraft serial no. ''120''), Flight Sub-Lieutenant Vivian Gaskell Blackburn (aircraft serial no. ''814'') and Flight Commander Douglas Austin Oliver (aircraft serial no. ''815'').</ref>
