By the end of the war, the IDF had penetrated deep into Syrian territory. Mount Hermon, which had been taken from Israel at the start of the war, returned to Israeli control. On the Southern Front, the Egyptian Third Army was surrounded in the Sinai, and Israeli troops had occupied the southern sector of the west bank of the Suez Canal fighting with the unconventional tactics of General Ariel Sharon. Nevertheless, despite these military achievements, Israel paid dearly in casualties, and the Egyptians still held some territory east of the canal, and none of the major cities were captured, although Suez was under siege.
