On 16 January 1957, while commander of the 10th military area and interarmy commander in Algiers, Salan was the target of an assassination attempt using a bazooka, resulting in the death of a French major. The attackers were French residents of Algiers who wanted to replace Salan with General René Cogny, whom they saw as a more energetic leader. The group's leader blamed the influence of a group of six prominent French politicians, which included future French Prime Minister Michel Debré (a senator at the time of the incident), as inspiration for the assassination attempt. However, he did not present any evidence to support the claim, and an investigation did not produce any definite answers about their involvement in the attack.
On May 13, 1958 as part of the Résurrection operation, Salan led an insurrection of the French military fighting in Algeria which called for the return to power of Charles De Gaulle. After his successful return to power, Charles De Gaulle appointed him general inspector of the army, forcing him to return to mainland France. After being put in early retirement by Charles De Gaulle, Raoul Salan went to Spain where he met with Ramón Serrano Súñer. He returned to Algeria to organize the putsch on 21 April 1961 with André Zeller, Edmond Jouhaud and Maurice Challe. After the failure of the putsch, he became the chief of OAS under the name Soleil(Sun). He was seconded by Edmond Jouhaud, Soleil-Bis. He was arrested in Algiers and charged with treason
