Attacks on U-123 during this patrol

27 Jun 1941
Having torpedoed two ships from convoy SL 78, the boat was depth charged for 11 hours, but escaped by going very deep - down to 654 feet (199m), below the range of British depth charges. (Sources: Blair, vol 1, page 302)

12 Aug 1941
The boat was attacked by convoy escorts near Portugal. 126 depth charges were dropped, including 30 "close by" as reported by the Germans, but caused only moderate damage. The boat returned to France, having been at sea for over 60 days when this attack took place. (Sources: Blair, vol 1, page 336)
