German submarine warfare

German submarine warfare during the World Wars involved Germany’s use of submarines (U-boats) to disrupt enemy shipping and cut off supplies. These submarines aimed to sink military and merchant vessels without warning, challenging traditional naval tactics and blockade efforts. In World War I, unrestricted U-boat attacks angered neutral countries and contributed to wider conflict. In World War II, Germany intensified submarine campaigns in the Atlantic, seeking to starve Britain and the Allies. This form of warfare was innovative, risky, and controversial, significantly impacting naval strategies and international laws on warfare at sea.
