Bastien-Thiry led the most prominent of several assassination attempts on de Gaulle. He and his group of three shooters (Lt. Alain de La Tocnaye, Jacques Prevost, and Georges Watin) made preparations in the Paris suburb of Petit-Clamart. On 22 August 1962, while Bastien-Thiry functioned as a lookout, de Gaulle's car (a Citroën DS) and some nearby shops were raked with machine-gun fire. De Gaulle and his wife and entourage escaped, uninjured. After the attempt, holes from fourteen bullets were found in the president's vehicle, one of which barely missed the president's head; another twenty were found to have struck the nearby Café Trianon; and an additional 187 spent shell casings were found on the pavement. De Gaulle was said to have credited the unusual resilience of the Citroën DS with saving his life: even though the shots had punctured two of the armoured tires, the car escaped at full speed.
