The U Boat Threat A blockage simply stops something getting through. In the case of World War I, blockades were set up to restrict the amount of supplies getting through to enemies ports. In earlier history surface ships simply blocking ships entering or leaving a port did this. 2. Unrestricted submarine warfare was set up in February 1915. It meant that any vessel heading for an English port would be fired upon. This was because it was thought that some ships carrying food were also carrying supplies for the war effort. 2 b. As the Germans could not break the British Naval blockade in the North Sea on German ports, they turned to using submarines to starve the British into submission, by destroying Allied shipping carrying food and raw material. Source 4 shows that the German Admiral Tirpitz thought that by also blockading our supplies, Britain would face a similar situation as their country. 3. The chart is source 2 shows three main points. Firstly, the graph starts at only 0.3 million tons of Allied shipping loss. This rises gradually due to the increase in German U Boats. Secondly, it can be seen that in 1917 the reintroduction of unrestricted submarine warfare has had a great effect on the quantity of Allied shipping sunk. The graph peaks at 6.25 million tons. Lastly, it is apparent that the anti submarine tactics dramatically reduced the amount of shipping lost. Depth charges were very effective, second only to mines. It is also thought that the decrease is due to destroyers travelling with large convoys in order to protect them. 4. There were a few serious food shortages and riots around Britain.

Patriotic books and toys were made for children, to encourage further support for the war effort.

Historian, Holger Herwig stated that with an average of twenty to thirty U Boats in the vast expanses of sea around Britain they were simply "insufficient do the job". However the German Admiralty may have realised that with a 50% loss rate they would have needed several hundred U Boats and they knew that the raw materials for U Boat building could be used elsewhere, such as in munitions and gun production. The Germans may have also been put off from building more U Boats as Britain quickly overcame the immediate threat with new technology.
