A convoy in sight

After hearing his colonel tell the A squadron commander to leave him alone, Robert decided, with his companions, to approach a stationary convoy, sitting not too far in the distance. They could not tell the nationality of the troops, as there transport was a mix of captured vehicles. As they approached within 200 yards, the transport bolted, in full flight, into the desert. As soon as they saw the convoy bolted, Robert took off after them, starting to fire. Suddenly, they saw a head, wearing a black beret lean out and wave "a white handkerchief". Robert yelled to his companions to stop firing. He spoke with the officer, who was relieved that they were British. They returned to the 3rd RTR and Robert explained that he had not been able to communicate. This is based on the account in Robert Crisp's book Brazen Chariots.
