F.O.A.S. insurgents sabotaged tram tracks and intersections in Algiers. [fact]
The next day, Saturday, the battle resumed with even greater fury. F.A.F. action groups poured oil on steep hillside tram tracks, and parked cars athwart intersections. An attack was made in the direction of the Palais d'Été, where a helicopter pad had been built, and it was rumoured that de Gaulle was going to fly in. Although, as far as bloodshed was concerned, nothing comparable to 24 January had yet occurred, the forces of order were, as Jouhaud had hoped, tiring; there were cases of detachments being submerged, or even being disarmed.
