"August 7th ... at 1.30 P.M.: I saw more dust coming down the road. Rose to the surface, and opened fire on troops marching towards Gallipoli. "E 11" was firing at the time I came up. I had stationed her to the north-east of Dohan Aslan Bank, and she first shelled the troops on a part of the road showing there, and then came down to my billet, where we both shelled them for the best part of an hour. I got off forty rounds, and about six of them burst in the middle of the troops. I had to put full range on the sights and aim at the top of the hill, so my shooting was not very accurate. "E 11" having a 12-pdr., did much more damage, and scattered the troops several times. Soon after 2 P.M. they started firing on us from the shore and out-ranging us." "E 11" on August 18th:-- "7 A.M.: Rose to surface near Dohan Asian Buoy to bombard troops, but they scattered before fire was opened. "8.30 A.M.: Rose to surface and opened fire on large convoy on road, several shells falling among them before they managed to scatter. "9 A.M.: Observed fire springing up where our shots had fallen. This rapidly increased in size, until in the afternoon and evening it had assumed very large proportions." A U-boat was captured by cavalry in 1918, but that case was perhaps exceptional. In the Napoleonic wars it was customary for English frigates to fire at French troops marching along the coast-roads of Spain, so that the E boats in the Marmora were only repeating history, but they certainly showed that the new weapon was a most disconcerting one for troops to have to reply to. I do not intend to fill pages with unexplained despatches, but the following extracts explain themselves, and, in any case, are too good to be omitted from any submarine history. "E 11" (Commander Nasmith):-- "May 23rd, 5.50 A.M.: Observed Turkish torpedo-gunboat at anchor off Constantinople. Attacked and sank her with port-bow torpedo, striking her amidships on the starboard side. While sinking she opened fire with a 6-pdr. gun, the first round hitting the foremost periscope. Proceeded to position north of Kalolimno Island. Rose to surface, and prepared damaged periscope for new top. "10.30 A.M.: Hands to bathe.
