The Irgun acted independently in the conquest of Jaffa (part of the proposed Arab State according to the UN Partition Plan). On April 25 Irgun units, about 600 strong, left the Irgun base in Ramat Gan towards Arab Jaffa. Difficult battles ensued, and the Irgun faced resistance from the Arabs as well as the British. Under the command of Amichai "Gidi" Paglin, the Irgun's chief operations officer, the Irgun captured the neighborhood of Manshiya, which threatened the city of Tel Aviv. Afterwards the force continued to the sea, towards the area of the port, and using mortars, shelled the southern neighborhoods.
