Germany’s U-boat campaign is now controversial, as Reichstag politicians have become sceptical about its ability to defeat Britain by the autumn. They are beginning to suspect that it has brought the USA into the war for nothing.
The U-boat crews themselves meanwhile are continuing to do their utmost. In the last month they have sunk another 600,000 tonnes of Allied shipping. According to the projections by Holtzendorff, the navy’s chief of staff, this rate of success should be enough to force Britain out of the war. However, although the British are hurting, there does not seem to be any obvious sign that they are about to collapse. For Germany it looks like the U-boat crews are doing all that was asked of them but that Holtzendorff has greatly underestimated the resilience of the enemy.
