The Ministry of Ungentlemanly Warfare

In the final months of 1941, Germany establishes dominance over the Atlantic Ocean. U-Boats wreak havoc on merchant vessels moving from the United States to the United Kingdom, creating a dire situation for supply lines crucial to the war effort.

In early 1942, Gus March-Phillips and Anders Lassen enjoy a moment of relaxation aboard their sailboat. Their drunken antics provoke a German naval party, resulting in their vessel being set ablaze by a furious German captain.

As the German sailors board their sailboat, they discover armed men hiding below deck. A fierce struggle leads to Anders slitting the German captain's throat, resulting in a violent massacre of the boarding party, showcasing their survival instincts.

Freddy Alvarez, a skilled diver, successfully plants explosives on the hull of a nearby German destroyer. The explosion cripples the destroyer, leading to its sinking and marking a crucial win for the Allied forces.

While the Allied forces face increasing threats, British commanders, including Winston Churchill, contend with relentless attacks from the Luftwaffe. With supply losses reaching 50% due to U-Boats, the situation becomes increasingly grim, leading to discussions of surrender.

In a bid for survival, Brigadier Colin Gubbins devises Operation Postmaster, a clandestine sabotage mission. The operation aims to disrupt the supply lines for Hitler's U-Boats based in neutral territory, risking escalation with Spain.

Gubbins recruits Gus March-Phillips to lead the mission, alongside undercover agents Marjorie Stewart and Richard Heron. Each member plays a vital role in the operation, with Marjorie's task being to seduce and distract the German commanding officer, Heinrich Luhr.

Gus and his crew, aboard the Maid of Honor fishing trawler, travel along the West African coast. Armed with explosives intended for the supply ship Duchessa D'Aosta, they prepare for the crucial phase of their mission.

Learning that fellow SOE agent Geoffrey Appleyard has been captured by the Gestapo, Gus opts for a risky detour to the Nazi-controlled Canary Islands. Understanding the importance of Appleyard's intelligence, they plan a daring raid to rescue him.

In an intense and dangerous operation, Gus leads his crew on a raid against a fortified German camp to rescue Appleyard. Anders displays his exceptional fighting skills, battling through the enemy's defenses to locate their captured ally.

Meanwhile, Marjorie and Heron successfully secure crucial cargo manifests from a German officer. They learn that the Duchessa is laden with arms and supplies, critical information that could turn the tide of their mission.

As the raid is planned, Gus receives alarming news that the Duchessa will depart ahead of schedule. Time is of the essence, and they must navigate through a British naval blockade to intercept the ship and execute their plan.

On the night of the operation, a well-planned diversion distracts German forces during a social event. Gus and his crew engage in a fierce battle against German soldiers to hijack the fortified Duchessa, risking everything for their mission.

After a tense fight, Gus and his crew successfully secure the Duchessa and deliver it to a British fleet outside Lagos. However, their triumph comes with unexpected consequences as they find themselves under arrest despite their heroic actions.

Their bravery earns the attention of Winston Churchill, who invites them to join his newly formed 'Ministry of Ungentlemanly Warfare'. Their exploits during the war inspire future tales, including those of the legendary Ian Fleming's James Bond.
