The air offensive began. The 3rd Division, minus the Guards Brigade, embarked on 1 November. The 45th Commando and 16th Parachute Brigade landed by sea and air on 5 November. Although landing forces quickly established control over major canal facilities, the Egyptians were able to sink obstacles in the canal, rendering it unusable. The Anglo-French air offensive suppressed Egyptian airfields not already attacked by the Israelis, but failed to destroy oil stocks or cripple the Egyptian army. Cairo Radio continued to broadcast. The 3rd Battalion Parachute group captured El Cap airfield by airborne assault. The remaining units, held back initially for deep airborne targets, travelled by sea to Port Said. The Commando Brigade captured all its objectives. The French parachutists took Port Fuad, opposite Port Said. Elements of the 16th Parachute Brigade led by Brigadier M.A.H. Butler and a contingent of the Royal Tank Regiment set off south along the canal bank on 6 November to capture Ismailia.
