On Yom Kippur in 1973 Egypt and Syria surprised Israel with a coordinated attack on two fronts. 80,000 Egyptian troops overran Israel's Bar Lev defensive line in the Sinai. 175 shells per second rained down on Israel's 500 defenders from 2000 Egyptian artillery pieces. On the Golan, Israeli tanks were outnumbered by the Syrians ten to one. It took Israel two full days, and thousands of casualties, to mobilize. By the time a truce went into effect three weeks later, Israeli commanders had marched within 25 miles of Damascus, and 63 miles of Cairo.
