Tension was heightened after the North Sea was declared a British 'military area' on 3 November 1914. Despite complaints about breaches of international law, however, most neutral merchant ships agreed to put into British ports for inspection and were subsequently escorted - minus any 'illegal' cargo bound for Germany - through the British-laid minefields to their final destinations.
The blockade strategy worked effectively. As a memorandum to the War Cabinet on 1 January 1917 stated, very few supplies were reaching Germany or its allies - either through the North Sea or through other areas such as Austria's Adriatic ports, subject to a French blockade since the first month of the war.
