Operation GLADIUS was part of Canada’s participation in the United Nations Disengagement Observer Force (UNDOF) on the Golan Heights between Israel and Syria.
Task Force Golan Heights consisted of three Canadian Armed Forces officers who served in the following appointments:
On 6 October 1973, Israel was attacked by its neighbours on two fronts: by Egypt on the Suez Canal and in the Sinai Peninsula, and by Syria on the Golan Heights. Known variously as the October War, the Ramadan War and the Yom Kippur War, the ensuing conflict lasted 19 days, despite diplomatic and military interventions by the United States and the Soviet Union, and a ceasefire ordered by the United Nations Security Council Resolution 338 on 23 October 1973.
On 25 October 1973, after ordering a second ceasefire with Resolution 339, the U.N. Security Council authorized the transfer of contingents from the United Nations Force in Cyprus to the Suez Canal zone to separate the Israeli and Egyptian forces deployed there, and thus bring a halt to hostilities on the southern front.
On the northern front, where an Israeli counter-attack had achieved a deep incursion into Syrian territory, the ceasefire in the south produced a hostile stalemate on the Golan Heights. Left without allies, the President of Syria cancelled a counter-offensive designed to repulse the Israeli invasion and ordered a ceasefire, while the Israelis held their positions. Months of skirmishing, artillery exchanges and air battles followed, culminating in the spring of 1974 with a failed Syrian attempt to recapture the summit of Mount Hermon, the highest point on the Golan Heights.
In March 1974, as the situation deteriorated on the Golan Heights, the United States resumed vigorous diplomatic efforts backed by the U.N. Security Council. Finally, on 31 May 1974, representatives of Israel and Syria signed the Agreement on Disengagement, and the U.N. Security Council adopted Resolution 350 to approve it and authorize the deployment of forces to monitor compliance.
The Agreement on Disengagement established the Area of Separation on the Golan Heights between the positions held by Syrian and Israeli forces on 25 October 1973. The Area of Separation is more than 75 km long and varies in width from about 10 km in the centre to 200 meters in the extreme south. Military forces are not permitted to enter it, and only residents may come and go freely within it. Each side of the Area of Separation is further buffered by an Area of Limitation, where the movement of belligerent forces is permitted under strictly controlled circumstances.
U.N. Security Council Resolution 350 of 31 May 1974 approved the Agreement on Disengagement and authorized the formation of the United Nations Disengagement Observer Force — UNDOF — with up to 1,250 military personnel and a mandate to:
Since its formation, UNDOF has had its mandate renewed every six months.
Canada’s involvement with UNDOF began with the launch of Operation DANACA in June 1974, which provided Canadian Forces logistics and signals units to support the entire mission.
Originally comprising more than 200 personnel, Operation DANACA was scaled back to 186 in 1992 and 1993, when UNDOF was reduced in size. By March 2006, when Operation DANACA closed, some 12,000 Canadian soldiers, sailors and air personnel had served on the Golan Heights.
The initial rotation of Operation GLADIUS consisted of four officers who remained in staff positions with UNDOF when the logistics unit deployed under Operation DANACA returned to Canada. The task force was reduced to two in July 2006, and increased to three in 2011.
