On 17 May the long-awaited Jacques Soustelle arrived in Algeria; his departure from Paris had been as spectacular in its way as his send-off from Algiers two years previously. Having failed to get away on the crucial night of the 13th, the former governor-general and arch-Gaullist had been under closest police surveillance, with some ten policemen watching his apartment in the Avenue Henri-Martin. On the 15th Soustelle let it be known that he was suffering from la grippe and confined to bed. Two days later friends drove a car into the courtyard, brazenly smuggled Soustelle out of Paris half-stifled under a rug reeking of moth-balls, and rushed him across the Swiss frontier where a plane ferried him to Algeria. It was a getaway worthy of his wartime operations.

QUESTION: Why did Soustelle need to evade police to reach Algeria in May, and what role would he play once there?
