The International Commission of Control and Supervision (ICCS) was an international monitoring force created on 27 January 1973. It was formed, following the signing of the Paris Peace Accords ("Paris Agreement on Ending the War and Restoring Peace in Vietnam"), to replace the similarly-named International Commission for Supervision and Control in Vietnam (ICSC). The ICCS was led by a director general, with Pudjo Prasetyo of Indonesia as the last officeholder.

Personnel

The organization comprised military and civilian staffs, provided by four nations. Initially, these were: Canada, Hungary, Indonesia and Poland (CHIP). The Canadian and Polish delegations had been present for nearly two decades, whilst the Hungarians and Indonesians were new to the task. For balance, the countries were expressly chosen to represent both the communist nations, Poland and Hungary, and the non-communist nations, Canada and Indonesia.

Canada had previously expressed dissatisfaction, and stayed largely to endure the successful establishment of the new body: It was a member from 29 January until 31 July 1973. The Canadian contingent was then replaced by one from Iran, which served from 1973 to 1975.

;Heads of Delegation

  • 1973–1973: Michel Gauvin. Canada.
  • 1973–197?: Eugeniusz Kulaga. Poland.
  • 1973–1974: Károly Kovács (1931–2007). Hungary.

;Strength

The four nations made the same contribution: 290 personnel.

  • Poland: 290
  • Hungary: 290
  • Indonesia: 290
  • Canada or Iran: 290
  • Total: 1,160

For reasons of distance and for reasons of safety, in a time of conflict, the ICCS often traveled by air. Requiring pilots experienced at flying over mountain and jungle, and men accustomed to the unpredictable military background of the region, the ICCS gave a contract to the locally well-established operation, Air America. Initially under the command of Col. J. A. Mitchell, of Canada, this organization gave a coat of white paint to its aircraft and panels indicating 'ICCS', to operate as: ICCS Air Services.

Losses

On 7 April 1973 in Quảng Trị Province, near Route 9, two ICCS helicopters operated by Air America were targeted by People's Army of Vietnam air-defense units. One was hit by anti-aircraft machine-gun fire and managed to land without casualties, the other was struck by a SA-7 missile, leaving no survivors. The helicopters were carrying teams on inspection, and therefore the casualties came from all four contributing nations, plus the contracted aircrew.

In all, apparently nine people were killed (some sources state eleven, but without any clarification):

  • Lieutenant Colonel Gunawan Salam Faiman (1931–1973), Army [ICCS Indonesia]
  • Captain Csaba Cziboly (1940–1973), Army [ICCS Hungary]
  • Major Aurél Dylski (1939–1973), Border Guards [ICCS Hungary] Capt. Laviolette was the only Canadian fatality with the ICCS, though others were lost with the ICC.
  • It seems there were none from Poland on this aircraft, which may possibly be explained by the presence of the two men from Hungary (for Poland, see: ICC)
  • PRG (Viet Cong) Liaison Mission: two officers (here unnamed) from Vietnam
  • CPT. Terry D. Clark (1944–1973), pilot [aircrew, US]
  • CPT. Charles L. Osterman (–1973), co-pilot [aircrew, US]

During the period there were 18,000 alleged cease-fire violations, which resulted in over 76,000 killed, wounded and missing to both sides: on 29 May 1973 the Canadians announced that they were withdrawing from the ICCS because they had come to supervise a ceasefire but were instead observing a war.
