The Battle of Westerplatte was the first battle of World War 2 in Europe. On September 1st, 1939, Germany began its invasion of Poland by bombarding the Polish garrison at Westerplatte, which was defended by 182 soldiers and 27 civilians. The Poles held off the German attacks for over a week with concealed firing positions and howitzer fire, inflicting casualties on the Germans. After days of bombardment by naval and artillery fire as well as air raids, the besieged Polish garrison surrendered on September 7th after running low on supplies, having defended Westerplatte bravely for over a week.
