Robert Taylor's painting portrays the renowned defiance of the U-Boat crews. Caught on the surface by a PBY Catalina the gun crews of a type VIIc     U-Boat are quickly into action. The 3.7cm anti-aircraft gun is hurriedly reloaded while on the upper platform the two 2cm anti-aircraft twins take chunks out of the Catalina's tail - enough damage to secure a respite from the attack. Soon they will dive to relative safety beneath the Atlantic swell.
