Here’s another Spitfire V, 4 cannon account from Malta.
Sgt. V. P. Brennan of 249 Squadron recorded his combat of 25 April 1942 as follows:
"I pulled up 30 or 40 feet underneath him. It was point blank range, and every detail of his machine stood out vividly. I could see his markings, his twin radiators, his retracted wheels, even the rivet heads of his fuselage. I gave him a second and a half with all four cannons. The result gave me a terrible fright. His starboard wing snapped off near the fuselage. It folded back, and banged against the fuselage. For a moment I thought it was going to tear away from his machine and come hurtling into my aircraft."
