During the early phase of the 1948 Palestine war (from November 29, 1947 to May 15, 1948), local Arab forces took control of the hills overlooking the road to Jerusalem (Highway 1), between Sha'ar HaGai (Bab el-Wad) and Al-Qastal, in effect besieging the city's Jewish population.
On May 15, 1948, British forces withdrew from the Latrun monastery and police fort that dominated the road and prevented supplies from reaching Jerusalem.
However, on the night of May 18, British-officered Arab Legion forces from Transjordan seized Latrun, and subsequent Jewish attempts to gain a foothold in the region failed.
