Algiers' population was awakened on 22 April at 7:00 am to a message read on the radio: "The army has seized control of Algeria and of the Sahara". The three rebel generals—Challe, Jouhaud, and Zeller—had the government's general delegate, Jean Morin, arrested as well as the National Minister of Public Transport, Robert Buron, who was visiting, and several civil and military authorities. Several regiments put themselves under the command of the insurrectionary generals. Gen. Jacques Faure, six other officers and several civilians were simultaneously arrested in Paris. At 5:00 pm, during the ministers' council, Charles de Gaulle declared: "Gentlemen, what is serious about this affair is that it isn't serious". He then proclaimed a state of emergency in Algeria, while left-wing parties, the trade union CGT and the NGO Ligue des droits de l'homme (LDH, Human Rights League) called to demonstrate against the military's coup d'état. The following day, on Sunday 23 April, Gen. Salan arrived in Algeria from Spain and refused to arm civilian activists. At 8:00 pm President de Gaulle appeared in his 1940s vintage military uniform on television, calling on French military personnel and civilians, in metropolitan France or in Algeria, to oppose the putsch: Due to the popularity of a recent invention, transistor radio, de Gaulle's call was heard by the conscript soldiers, who refused en masse to follow the professional soldiers' call for insurgency and in some cases jailed their officers. The putsch met with widespread opposition, largely in the form of civil resistance, including a one-hour general strike called by the trade unions the day after de Gaulle's broadcast. Within the army itself much depended on the position taken by individual senior officers. The 13th Light Division of Infantry, responsible for the strategic Zone Sud Oranais (south Oran zone) and including Foreign Legion units, followed the lead of its commander, Gen. Philippe Ginestet, in remaining loyal to the government in Paris. Ginestet was subsequently assassinated by the OAS in retaliation. On Tuesday 25 April government authorities in Paris ordered the explosion of the atomic bomb Gerboise Verte (lit. "green jerboa") in the Sahara as part of a scheduled testing program. Gerboise Verte exploded at 6:05 am. While the test and test site were already prepped as part of the French national nuclear program, the test timeline appears to have been accelerated to ensure that the security of the device was not compromised.
