5.45 P.M. Position W. 3/4´ N. 23´ from Heligoland. Nothing in sight except numerous trawlers, chiefly sailing. Turned to N. 60 W., 9 knots. Sea rough. 8.10 P.M. Increased to 10-1/2 knots. Many trawlers in sight at nightfall. 9.30 P.M. Stopped. Dived 50 feet on "grouper down" till-- _August 7th_-- 2 A.M. Rose. Very dark; dived 50 feet. 3.15 A.M. Rose. 3.30 A.M. Proceeded under one engine, 8 knots, working round a large fleet of sailing trawlers making to southward; making for route of warships seen yesterday. 6 A.M. Altered course 12 knots. 7.45 A.M. Altered course S.E. 8.15 A.M. Sighted German submarine on surface, S.E. 4 to 5 miles distant, beam to beam. Dived to attack. At first thought she was stopped and had then dived, not sighting her through periscope till 8.45. 8.45. A.M. Sighted her steaming west, 4 or 5 miles off. Followed, diving. 9.30 A.M. Rose. Submarine not in sight. Followed, diving, for 3/4 hour, in hopes of finding her stopped. 10.30 A.M. Proceeded S. 56 E., 12 knots. 12 noon. Stopped to let steam trawler pass across horizon, ahead. _Note._--Since about 7 A.M. I had given up the idea of trying to keep out of sight of trawlers, merely avoiding going within a mile of them. 12.10 P.M. Proceeded. 12.54 P.M. Altered course south, observed position being further north than intended. The steam trawler sighted at noon seemed suspicious of E 6, altering course so as to keep me in sight without getting close. 3.30 P.M. Turned and steered for trawler, signalling her to show colours (German), and to stop. Trawler fitted with W/T. Crossed her bows and shaped course N. 87 W., 14 knots. Position then N. 43 W. 37´ from Heligoland. Trawler proceeded, apparently shaping course for Emden. Steered to avoid our T.B.D. patrol. _August 8th_-- 6.30 A.M. Made Swarte Bank Light-vessel. Proceeded to Lowestoft to report. _Note._--The Heligoland Bight contained a very large number of trawlers, chiefly sailing, including a few which were apparently Dutch; they became more numerous closer in to Heligoland. I did not notice W/T in any except the one I spoke. I have the honour to be, sir, your obedient servant, (Sd.) G. P. TALBOT, Lieutenant-Commander. The Commodore (S), H.M.S. _Maidstone_. That is the sort of way the submarine officers describe their experiences. The method is curt and unsatisfying somehow. I will try and give an idea of a submarine captain describing a trip during, say, the winter of 1915-1916, to an army brother:--
