 appeared,
E18 dived to the sea bed but was easily visible from the air. E18 was then straddled with 12 bombs which caused no damage other than some embarrassment for Halahan in being caught unaware. The fact E18 was surfaced wasn't passed on via Halahan's patrol report, he stated he was submerged at 20 ft, and an inquiry into submarine visibility from the air led E18 being painted in her camouflage scheme. Strangely there is no German claim of an attack on a submarine - the Zeppelins in the air that day in this area were, L4, L6 and L7, none of which sighted a submarine let alone attacked one. L6 was the closest to E18s position when a Zeppelin was sighted but she moved away to the west when the explosions occurred. German minesweeping divisions were exploding mines during the time of the alleged attack which could explain what the crew of E18 heard while submerged.

 on the night of the 8-9th September. During the passage E19 at one stage found herself only metres from E18s stern and decided not to enter together. E18 encountered two German destroyers. She dived into water only 23 feet (7 m) deep and — for almost three hours — progressed by crashing into the seabed and rising back up to break the surface. After several hours resting in deep water she surfaced in the morning only to be fired on by the cruiser Amazone; once again she dived to the bottom. The German cruiser and attending destroyers then began to criss-cross over the top of E18 knowing her batteries would be very low. E18 had to sit it out on the bottom until the German left the area. E18 was lucky the German ships were not then equipped with depth charge

A depth charge is an anti-submarine warfare weapon intended to destroy or cripple a target submarine by the shock of exploding near it. Most use explosives and a fuze set to go off at a preselected depth in the ocean. Depth charges can be dropped by either surface ships, patrol aircraft, or from...

She returned to Reval on 16 October 1915 at 1700 hrs.

E18 departed for her third patrol on 9 November 1915, and was to patrol the Swedish trade routes, she arrived back at Reval on 15 November 1915 having sighted nothing of significance. During this patrol the crew had missed the visit of the Tzar.

Her fourth patrol was to patrol off Libau and try and find a way through the mine fields by following the courses of ships coming and going. She departed for this patrol on 30 November 1915 and returned on the 4 December 1915. This was her last patrol for 1915.

 left the same day. Records differ on her exact fate, but it is certain neither she or any of her crew ever returned.

The diary of Francis Goodhart, commander of
E8, states that E1 and the Russian Bars departed at 1400 hrs, E8, E18 and the Russian Gerpard left port together at 1800 hrs on 25 May; E8 's patrol was uneventful, and she returned to Reval on the 31st. However, E18 failed to return; by 5 June Goodhart noted that the crews were "very worried". On the 6th, he noted that he had "Heard from Essen that their W.T. had vaguely indicated presence of a submarine off Redshoff" on Tuesday'. Very slender hope..." By the next day, 8 June, he recorded that a meeting had noted she had sailed with only 15 days food; the situation was "very hopeless now, I fear. No news whatsoever" By the 9 June E8's officers began collecting the belongings of E18's Halahan, Landale and Colson from their cabins. On a sad note Goodhart learnt that Halahan had his future told by a local woman prior to this last patrol. She told him he was in grave danger, this affected the superstitious Halahan who then asked the wife of the British Vice Consul

 in Reval to send a wire to his family before they got the official Navy telegram in case something happened to him. This indeed she did when Halahan failed to return.

Michael Wilson, a historian, records that E8 and E18 sailed on the 25th and parted the next day. On the 26th, at 4:42 PM, E18 torpedoed the German destroyer V100, blowing off her bow. Had it not been for the calm seas, it is likely she would have sank from the damage; as it was, she was towed back to port with several of her crew killed, requiring major repairs. Two days later, on the 28th, E18 was sighted by a German aircraft off Memel

 (now Klaipėda, Lithuania),
E18 was last sighted on the 1 June 1916 at 1500 hrs sailing north by the German U-boat UB-30 northwest of Steinort. Wilson further states that it is believed she was lost "most likely by striking a mine" on her return to Reval west of Osel

. The logs of the German destroyers with
V100 also support the same dates as Goodhart's diary and Wilson's observations.

Various sources record her simply as having been sunk on 24 May by a German decoy ship

, though this clashes with the known attack on
V100 on the 26th and the observations reported by Wilson and Goodhart in subsequent days. It is quite possible that this is a garbling of an encounter between one of the Russian submarines and a decoy vessel around the same time. The German decoy ship Kronprinz Wilhelm

When people research the subject of E18, 11 June 1916 is stated as the date on the crews papers as being lost at sea, as they had no idea when and where E18 was lost at the time this date was purely for administration purposes to close the books on E18.
