 At the end of May , David Ben @-@ Gurion was convinced that the Arab Legion expected to take control of all Jerusalem . Moreover , after the fighting , the situation there deteriorated : the Jewish community had very small reserves of fuel , bread , sugar and tea , which would last for only 10 days , and water for 3 months . In Glubb 's opinion , the aim was still to prevent the Israelis from reinforcing the city and taking control of its Arab part . On 29 May , the UN Security Council announced its intention to impose a ceasefire for 4 weeks , which would prevent further capture of territory and thus prevent resupplying the besieged city .
