1941. The Battle of the Atlantic is a disaster. Thousands of supply ships carrying vital food and fuel from North America to Britain are being torpedoed by German U-boats. Britain is only weeks away from starvation and crushing defeat.

In the first week of 1942 a group of unlikely heroes - a retired naval captain and a clutch of brilliant young women - gather to form a secret strategy unit. 

The Western Approaches Tactical Unit spends days and nights designing and playing war games in an effort to crack the U-boat tactics. As the U-boat wolfpacks continue to prey upon the supply ships, it is race against time to save Britain.

With novelistic flair, investigative journalist Simon Parkin shines a light on this riveting true story of war at sea.
