the Egyptian second army's supply lines, but his division was halted south of the Fresh Water Canal. Abraham Adan's division passed over the bridgehead into Africa, advancing to within 101 kilometers of Cairo. His division managed to encircle Suez, cutting off and encircling the Third Army. Tensions between the two generals followed Sharon's decision, but a military tribunal later found his action was militarily effective. Sharon's complex ground maneuver is regarded as a decisive move in the Yom Kippur War, undermining the Egyptian Second Army and encircling the Egyptian Third Army. This move was regarded by many Israelis as the turning point of the war in the Sinai front. Thus, Sharon is widely viewed as the hero of the Yom Kippur War, responsible for Israel's ground victory in the Sinai in 1973. A photo of Sharon wearing a head bandage on the Suez Canal became a famous symbol of Israeli military prowess. Sharon's political positions were controversial, and he was relieved of duty in February 1974. Bar Lev Line Following Israel's victory in the six-day war, the war of attrition at the Suez Canal began. The Egyptians began firing in provocation against the Israeli forces posted on the eastern part of the canal. Haim Bar Lev, Israel's chief of staff, suggested that Israel construct a border line to protect its southern border. A wall of sand and earth raised along almost the entire length of the Suez Canal would both allow observation of Egyptian forces and conceal the movements of Israeli troops on the eastern side. This line, named after the chief of staff Haim Bar Lev, became known as the Bar Lev Line. It included at least thirty strong points stretching over almost 200 kilometers. Bar Lev suggested that such a line would defend against any major Egyptian assault across the canal, and was expected to function as a "graveyard for Egyptian troops". Moshe Dayan described it as "one of the best anti-tank ditches in the world." Sharon, and Israel Tal on the other hand, vigorously opposed the line. Sharon said that it would pin down large military formations that would be sitting ducks for deadly artillery attacks, and cited the opinion of Rabbi Menachem M. Schneerson, who explained him "the great military disaster such a line could bring." Notwithstanding, it was completed in spring 1970. During the Yom Kippur War, Egyptian forces successfully breached the Bar Lev Line
