Encyclopedia - HMS Birmingham & U-15
The British 5,400 ton light
cruiser HMS Birmingham was responsible for sinking the first German
submarine of the First World War. Commanded by Captain Arthur Duff HMS
Birmingham - of 'Chatham' class - knocked out both the periscope and
conning tower of German U-15 on 9 August 1914 with a salvo of six shots from
the light cruiser's guns east of the Orkneys while the submarine was
attempting to move in for an attack.
Having done so Duff issued instructions that the cruiser be directed at the U-boat at full speed.
Turning HMS Birmingham's helm the cruiser was brought around in order
that her bows faced the crippled submarine.
Thus Duff rammed the German submarine at 25 mph (40 kph), which quickly rolled over and sank, killing its crew of 23.
HMS Birmingham subsequently took part at both the Battle of Heligoland Bight and the Battle of Jutland.
A 'Woolly Bear' comprised a German shrapnel shell, which burst with a cloud-like explosion.
