October 6 in Military History — On This Day

Crossing of the Suez Canal

At 2:00 p.m. on Yom Kippur — the Day of Atonement, when most Israeli soldiers were fasting and radio stations were off the air — Egyptian forces launched the most sophisticated river crossing operation since World War II. Water cannons dissolved Israeli sand embankments, 8,000 troops crossed the canal in the first hour on rubber boats, and 100,000 soldiers poured across in the first day. The Bar-Lev Line, Israel's supposedly impregnable defensive fortification, was overrun.

The canal crossing was Egypt's greatest military achievement since Thutmose III. The use of high-pressure water hoses to breach Israeli sand fortifications — a suggestion by a civilian engineer — was a stroke of operational ingenuity. The shock to Israeli military confidence was profound. The myth of Israeli invincibility, born in 1967, died on October 6, 1973.

Battle of the Valley of Tears

On the Golan Heights, 180 Israeli tanks faced 1,400 Syrian tanks. For three days, Col. Avigdor Kahalani's 77th Battalion fought in the 'Valley of Tears' against overwhelming odds, withdrawing and counterattacking, losing tanks and crews until they ran out of ammunition and had to scavenge from destroyed vehicles. When the last Syrian attack came, Kahalani had seven tanks operational. The Syrians, not knowing how few remained, withdrew.

The Valley of Tears was arguably the most critical battle of the war. If Syria had broken through the Golan, their armor would have been 30 miles from Haifa with nothing to stop them. The desperate three-day stand by outnumbered Israeli tank crews — many fighting in damaged vehicles — bought the time for reinforcements to arrive. The battle is studied in military academies worldwide as a case study in armored warfare and command under pressure.

Yom Kippur War — Egypt and Syria Surprise Israel

Egypt and Syria launched a coordinated surprise attack on Israel during the holiest day of the Jewish calendar, achieving complete tactical surprise. Egyptian forces crossed the Suez Canal in a brilliant operation while Syrian tanks poured into the Golan Heights.

The Yom Kippur War showed Israel was not invulnerable, triggered the 1973 oil embargo, and ultimately led to the Camp David Accords and peace between Egypt and Israel.

Outcome

Israel survives; Egyptian-Israeli peace negotiations begin
