Infamous Assassinations: Part 18: Attempts on General de Gaulle

There were three attempts to kill General de Gaulle, all of which were unsuccessful. The first was by German snipers in Paris 1945. The second was on 8 September 1961, when a plastic charge was fired at his car by a gang controlled by Raoul Salan. The third attempt was on 22 August 1962, when his car was raked by machine-gun fire which shattered the rear window and burst two tyres. The General escaped all three attempts, but was there a fourth which was not reported?
