In late 1942, German U-boats were sinking Allied merchant ships faster than they could be replaced, pushing Britain to the brink of starvation in the 'Black Pit' of the mid-Atlantic.

In this episode Roger Moorhouse is joined by Saul David as he dives into the most critical period of the Battle of the Atlantic, from the peak losses of March 1943 to the stunning Allied victory in 'Black May.'

They explore the high-stakes technological race—including the deployment of long-range aircraft, advanced radar, sonar, and breaking the Enigma code—that transformed the Allies from prey to predator and secured the lifeline that made the liberation of Europe possible.
