In 1915 a man well known to the Submarine Service--a Submarine Flotilla Chaplain--went out in "E 4," under Commander Leir, to see for himself how his messmates spent their time on patrol. It is usual in patrol submarines to have as few hands on deck as possible--in fact, nobody is allowed on deck beyond the officer on watch, a look-out, and perhaps one other. On this occasion "E 4," having the chaplain on board, decided to call her crew to prayers on deck while they were on passage to their area, but the crowded state of the bridge a few minutes later was rather a handicap to quick diving when a Zeppelin interrupted the service. The padre, however, had no intention of being a mere passenger, and during the trip he, after a little training, was able to stand his trick on a hydroplane wheel when diving. A survivor from an armed trawler torpedoed by "E 4" was also a grateful guest, and the curious sight might occasionally have been seen of a German prisoner and a naval chaplain sitting on adjacent stools and working the diving-wheels in harmony. What the padre really thought of the trip is not known, but there was no doubt about his having the attention and respect of his somewhat reckless flock on his return to harbour. "E 4" was the sort of boat to take a passage in if one wished to see life in the Bight thoroughly. On one occasion she rose to the surface and chased a U-boat up to Heligoland, endeavouring to instil into her opponent a spirit of pugnacity by continual signals on the arc-lamp, such as, "How many women and children have you killed to-day?" and in a sort of meet-you-half-way tone, "Gott strafe England!" The U-boat, however, was not playing, and used her superior speed to get away (which was perhaps as well, because, if she'd only known it, "E 4" at the time, had no gun).
