The novelty of this occasion was that we were told to fire our main armament, the Petard, against the sea wall there, to see if we could knock it down and then drive our tanks up over the rubble and move inland against an imaginary enemy. I should explain that the Petard was a short (80 yard) range weapon which carried the formidable amount of 26 lbs of high explosive. A wall of anything greater than 5 feet in height is a complete obstacle to a tank and many such walls existed behind the beaches in France.
I fire red Very flares, wave and drop a message in a container in which I inform my tank colleagues who and what are coming in their direction three kilometres away, assuming they both keep to the same course. By dipping my aircraft towards the spot where the T-34s are travelling at the moment I tip them off to the nearness of the enemy. Both parties drive steadily on.
