After the 1st Foreign Parachute Battalion 1e BEP became the 1st Foreign Parachute Regiment 1e REP, Pierre was passed over for command on 6 February 1956, instead serving as second-in-command, this time to Colonel Albert Brothier which he assumed but was deeply disappointed. The regiment was put on alert on 1 August 1956 after the preparation of the campaign in Egypt; Pierre embarked on October 31, however, his views and reservations of this disembarking were well known. This beautiful instrument of combat which became a regiment didn't serve any worthy cause. Nevertheless, a new mission was confined to Pierre, which was to end in the insurgency in Algeria, a police mission which no one wanted or liked but a mission which had to be executed successfully. Pierre retook command of the 1st Foreign Parachute Regiment in March 1957.
