What happened 1960 AD in Algeria

Most of the Army heeded De Gaulle's call, and the siege of Algiers ended on February 1 with Lagaillarde surrendering to General Challe's command of the French Army in Algeria.

On 13 February 1960, France became the world's fourth nuclear power when a high-powered nuclear device was exploded in the Sahara some 700 miles south-south-west of Algiers.

The loss of many ultra leaders who were imprisoned or transferred to other areas did not deter the French Algeria militants. Sent to prison in Paris and then paroled, Lagaillarde fled to Spain. There, with another French army officer, Raoul Salan, who had entered clandestinely, and with Jean-Jacques Susini, he created the Organisation armée secrète (Secret Army Organization, OAS) on December 3, 1960, with the purpose of continuing the fight for French Algeria. Highly organized and well-armed, the OAS stepped up its terrorist activities, which were directed against both Algerians and pro-government French citizens, as the move toward negotiated settlement of the war and self-determination gained momentum.
