The Germans are hoping that their U-boats will force Britain out of the war by the autumn. Last month the submarines sunk a record quantity of Allied shipping. As a trading nation, Britain needs its merchant fleet to survive. If the Germans can continue to destroy its ships faster than they can be rebuilt then Britain will be reduced to poverty and starvation.
The British are trying various measures to counter the U-boat threat. Food production at home is being increased and ship building is being accelerated. And now they try a novel tactic to protect the ships while they are at sea. Instead of having merchantmen sail individually, easy targets for the German submarines, today the first convoy of 17 ships, escorted by warships of the British navy, sets sail for Britain from Gibraltar. Some fear that having all these ships sail together presents the Germans with too tempting a target, but the hope is that they will be protected from the U-boats’ depredations by their escorts.
