Four events broke the insurrection: the first was the withdrawal from Algiers by Delouvrier and Challe, with its implied threat that at least part of the armed forces might be prepared to face civil war; the second was the inability of Ortiz and the "ultras" to gain any palpable Muslim support; the third was the chance break in the weather and the deluging rain it brought; and the fourth was the impact of de Gaulle's speech of the 29th. But of all four it was de Gaulle's voice that proved the most effective.
