March 1917: Submarine warfare

With the First World War entering its 34th month and — as a letter elsewhere in the issue points out — mobilisation of British troops still underway, the threat of German submarines was preying heavily on the public mind. U-boats seems to be an invisible, intangible weapon which could strike with impunity at absolutely no risk to themselves, and the public was becoming increasingly nervous that British military and merchant shipping would be unable to reach their targets, and that shops would run out of stocks. To allay these fears, the First Lord of the Admiralty, Sir Edward Carson, used a regular speech on the Navy’s estimates of enemy damage to point out that the Royal Navy was in fact very effective at countering U-boats, as The Engineer reported.

The speech was particularly in response to reports in the launch of a German policy of unlimited U-boat warfare, with the hope that for every vessel sunk, another dozen would be scared away; in early March, an entire fleet of Dutch merchant ships were sunk in the Channel (especially alarming as the Dutch were neutral in that conflict). However, Carson said. over an 18-day period the Royal Navy had detected and attacked U-boats on ‘no fewer than 40 occasions’. The Engineer commented that ‘if the figure for these 18 days are to be taken as an average, the mortality among the marauders must indeed be formidable.  Our wonder increases at the folly of the German rulers in risking the active hostility of powerful neutrals for the sake of ruthlessly employing an arm whose limitations grow more obvious every day.’
