The work of RAF Coastal Command aircraft engaged in anti-U-boat patrols was long and for the most part uneventful. Day after day they made sweeps far out into the Atlantic, the crew constantly scanning the ocean for any sign of the lurking threat to Allied shipping. Weeks or months might pass before they were called into action.
To catch a U-boat on the surface was rare. Attacking a U-boat before it had any chance to defend itself was rarer. To disable the boat on the surface was exceptionally rare - it appears to have been a unique event.
