1941Truant (N68)HMS Truant damages the small Italian tanker Prometeo with gunfire off Tripoli, Libya.
1942Unbroken (P42)Lands two secret agents near Antibes (France)
HMS Unbroken silently slipped towards the French coastline. On board were operatives from the Special Operations Executive (SOE), the Wartime intelligence agency tasked with espionage, reconnaissance and sabotage in occupied Europe.

Under the daring command of Alistair Mars, HMS Unbroken successfully delivered the Wartime agents, led by Peter Churchill, to Antibes bay. Churchill was able to link up with the French Resistance and carry the fight to the Nazi occupiers.

Led by Peter Churchill, the SOE agents used inflatable boats to paddle from the submarine in Antibes bay to the shore. From there they made their way to the French Resistance, bringing them directives, helping to improve their communications, and arranging help for those brave fighters who had been arrested. Peter Churchill’s exploits were later portrayed by Trevor Howard in the 1950 film "Odette".
