In 1973, Israeli forces crossed to the western side of the Suez Canal in a decisive battle of the Yom Kippur War. A division led by Ariel Sharon had attacked a weak point in the Egyptian "seam line" between the Egyptian second Army in the north and the Egyptian third Army in the south. In some of the most brutal fighting of the war, the Israelis opened a hole in the Egyptian line and reached the Suez Canal. A small force crossed the canal and created a bridgehead on the other side. A few days later, Israeli troops trapped the Egyptian Third Army, leaving it without any means of resupply, thus effectively ending the Yom Kippur War.
