In June 1940, Italy declared war on the British Commonwealth and sided with Germany. Within a month, Italian planes bombed Tel Aviv and Haifa, inflicting multiple casualties. In May 1941, the Palmach was established to defend the Yishuv against the planned Axis invasion through North Africa. The British refusal to provide arms to the Jews, even when Rommel's forces were advancing through Egypt in June 1942 (intent on occupying Palestine) and the 1939 White Paper, led to the emergence of a Zionist leadership in Palestine that believed conflict with Britain was inevitable. Despite this, the Jewish Agency called on Palestine's Jewish youth to volunteer for the British Army (both men and women). 30,000 Palestinian Jews and 12,000 Palestinian Arabs enlisted in the British armed forces during the war. In June 1944 the British agreed to create a Jewish Brigade that would fight in Italy.
