In November 1947, the Jewish insurgency came to an end as the UN approved of the partition of Palestine, and the British had announced their intention to withdraw the previous month. As the British left and the 1947-48 Civil War in Mandatory Palestine got underway, the Irgun came out of the underground and began to function more as a standing army rather an underground organization. It began openly recruiting, training, and raising funds, and established bases, including training facilities. It also introduced field communications and created a medical unit and supply service.
