craft. On the
1st of April, 1915, the British Government's press bureau announced
that bombs had been dropped, with unknown success, on two German
submarines lying there, and that on the same day a British airman
had flown over Hoboken and had seen submarines in building there.

The steamship _Lockwood_, while off Start Point in Devonshire,
was hit abaft the engine room by a German torpedo on the morning
of April 2, 1915, and though she went down almost immediately,
her crew was able to get off in small boats and were picked up by
fishing trawlers.

The _U-28_, which had done such effective work for the Germans
during the month of March, 1915, was relieved of duty near the
British Isles during the first week of April by the _U-31_, which
sank the Russian bark _Hermes_ and the British steamship _Olivine_
off the coast of Wales on April 5, 1915.

The British admiralty decided in April, 1915, to use some other
means besides the employment of torpedo boats and destroyers to
keep watch for German submarines, and innocent-looking fishing
trawlers were used for the purpose. While these could give no fight
against a submarine, it was intended that they would carefully make
for land to report after sighting one of the hostile craft. The
Germans, discovering this strategy, then began to sink trawlers
when they found them. On the morning of April 5, 1915, one of these
small craft was sighted and chased by the _U-20_. After a pursuit
of an hour or more the German ship was near enough for members of
her crew to fire on the trawler with rifles. Her crew got into
the small boat and were picked up later by a steamer. The trawler
was sent to the bottom.

The _U-20_ still kept up her raiding. On the 5th of April, 1915,
she overtook the steamer _Northland_, a 2,000-ton ship, and torpedoed
her off Beachy Head. The crew of the steamer were able to escape,
although their ship went down only ten minutes after the submarine
caught up with it.

The use of nets to catch submarines was vindicated, when on the 6th
of April, 1915, one of these vessels became entangled in a steel
net near Dover and was held fast. The loss of the _U-29_, which
was commanded by the famous Otto von Weddigen, who commanded the
_U-9_ when she sank the _Hogue, Cressy_, and _Aboukir_ in September,
1914, was confirmed by a report issued by the German admiralty on
April 7, 1915, after rumors of her loss had circulated throughout
England and France for a number of wee
