Operation ''Vigorous'', June 1942
Pages 12

Towards the end of the air attacks, at 2000 on the 14th, a submarine appeared on the starboard bow of the force and nearly torpedoed the Pakenham in the outer screen; she was attacked with depth charges, but without success. A few minutes later, at sunset, the fighter patrol reported a flotilla of six motor torpedo craft-E-boats4-to the north-westward, and shortly afterwards the enemy were seen hull down from the Euryalus on the starboard bow of the convoy. The fighters were directed to attack; but the E-boats had an escort of German fighters, which held off the one British aircraft that complied, the others being engaged with enemy bombers. Accordingly, the E-boats remained undisturbed.
