Operation Postmaster, a bold and covert British commando operation during World War II, exemplifies the ingenuity and daring of Allied special forces. Conducted in January 1942 by the Special Operations Executive (SOE), this raid targeted Axis shipping in the neutral port of Santa Isabel on the Spanish-controlled island of Fernando Po (now Bioko in Equatorial Guinea). We delve into the planning, execution, and significance of Operation Postmaster, highlighting the strategic brilliance and audacity of those involved.
Background and Strategic Importance
By late 1941, the Allied forces were searching for ways to disrupt Axis operations across various theatres of the war. The SOE, established by Prime Minister Winston Churchill to “set Europe ablaze,” specialized in sabotage and unconventional warfare. Their mission was to strike at the Axis powers through guerrilla tactics, espionage, and sabotage, often behind enemy lines.
Santa Isabel was a strategic location for Axis shipping. Several Italian and German ships sought refuge in the port to avoid capture or destruction by the Allied navies. These vessels, including the Italian merchant ship Duchessa d’Aosta and the German ships Likomba and Bibundi, represented potential threats as they could be used to resupply Axis submarines and surface raiders operating in the Atlantic. Disabling these ships would hinder Axis maritime logistics and deny them safe havens.

Planning the Raid
The operation was conceived by Major Gustavus March-Phillipps, the leader of the Small Scale Raiding Force (SSRF), a unit within the SOE. The plan was audacious: infiltrate the neutral port, seize the Axis ships, and tow them to Allied-controlled Nigeria. This required meticulous planning, precise execution, and above all, maintaining the element of surprise to avoid diplomatic fallout with Spain, a neutral country during the war.
Key figures in the planning included Major March-Phillipps, Captain Graham Hayes, and Lieutenant Geoffrey Appleyard. They assembled a team of commandos from the SSRF and sailors from the Royal Navy, ensuring that each member was briefed thoroughly and prepared for the complex mission.

The team utilized two tugs, Nuneaton and Nigerian, camouflaged to blend into the local environment. These tugs would serve as the primary vessels for the raid, equipped with the necessary tools for boarding and securing the target ships. The operation also required coordination with the Royal Navy, which provided support and backup if things went awry.
Detailed Planning and Preparation
The meticulous planning phase of Operation Postmaster was critical to its success. Intelligence gathering played a key role, with agents providing detailed reports on the layout of the port, the positioning of the Axis ships, and the routines of the crews.
This information was crucial for formulating a plan that maximized the chances of success while minimizing risks.
Training for the raid was intense. The commandos and sailors rehearsed the boarding techniques, practiced handling explosives, and familiarized themselves with the layout of the target ships. The training was conducted under conditions that simulated the actual raid environment as closely as possible, including night operations and silent approaches.
A crucial element of the preparation was the customization of the tugs. The Nuneaton and Nigerian were modified to carry the commandos and the equipment needed for the operation. They were also fitted with additional fuel tanks to ensure they could make the return trip to Nigeria without refuelling, which would be impossible once the raid commenced.
Execution of the Raid
On the night of January 14-15, 1942, the commandos set out under the cover of darkness. The approach to Santa Isabel was fraught with risk. The neutral status of the port meant any discovery could result in severe diplomatic repercussions, potentially damaging Allied relations with Spain.
Upon reaching the harbour, the commandos split into teams. One team, led by Captain Hayes, was tasked with boarding and securing the Duchessa d’Aosta. Another team, led by Lieutenant Appleyard, targeted the Likomba and Bibundi. They used grappling hooks and scaling ladders to silently board the ships, overcoming minimal resistance as the crew members were caught off guard.
The commandos’ training and preparation paid off. They swiftly overpowered the minimal guards, neutralized the crews without lethal force, and began the process of preparing the ships for towing. The efficiency of the operation was crucial to avoid detection and ensure a swift departure from the port.
Once on board, the commandos quickly overpowered the crews and began the process of preparing the ships for towing. They disabled the ships’ communications equipment to prevent any distress signals from being sent. The meticulous preparation paid off as the commandos successfully secured the ships and began towing them out of the harbour.
Challenges and Adaptations
Despite the meticulous planning, the operation was not without its challenges. The commandos encountered unforeseen obstacles, such as the difficulty in securing the tow lines to the ships and minor technical issues with the tugs. The tight timeline meant that any delay could jeopardize the entire mission.
One significant challenge was the potential for interference from the Spanish authorities. Although Spain was neutral, any discovery of the raid could lead to diplomatic complications.

The commandos demonstrated remarkable adaptability in overcoming these challenges. They improvised solutions on the spot, using their training and resourcefulness to address issues as they arose. This ability to adapt under pressure was a testament to their professionalism and the effectiveness of their preparation.
As the tugs entered the harbour, the raiders assembled on deck, with Vulcan carrying March-Phillipps and Appleyard as his second-in-command heading for the Duchessa d’Aosta. The few men who could be seen on the after deck o f the merchant vessel, seemed to take no notice of the tug but a torch beam was pointed in their general direction.
Simultaneously, Folbots commanded by Hayes from Nuneaton were paddling towards Likomba which was moored to Burundi. They were spotted and challenged by a watchman on Burundi, but he fell for the reply that it was the ship’s captain coming back on board.
The men from the canoes then boarded Burundi, and the two-man crew on watch jumped overboard. Explosive charges were attached to the anchor chain, and the commandos guided Nuneaton alongside Likomba to take her and Burundi in tow.
At the appointed time the charges were detonated and the anchors released allowing Nuneaton to start the tow of Likomba out of the harbour. Eleven men from Vulcan boarded Duchessa d’Aosta; one group attached charges to the anchor chains, while a second group searched below-decks and manage to collect some prisoners.
The anchor chains were cut by the explosive allowing the Vulcan to start the tow of the Duchessa d’Aosta out of the harbour. The explosions hadn’t gone unnoticed triggering Anti-aircraft emplacements to open fire at imaginary targets, believing the explosions to have been caused by an aerial attack. Meanwhile many of the town’s population gathered on the pier for a better view. No attempt was made to stop the ships from leaving. Unbelievably, the six-inch guns protecting the harbour from attack from the sea remained silent. The operation had taken just 30 minutes, without so much as a scratch to the members of the raiding party.
15 January 1942, and underway, March-Phillipps had placed guards to secure the 29 prisoners they had taken, but in the evening they experienced engine trouble tugs’ engines straining to hold the tow of the captured ships. On the morning of the 16th, Vulcan reached the rendezvous point and was “captured” at sea by HMS Violet but Nuneaton, whose engines were packing up, contacted the collier Ilorin by semaphore, which in turn contacted Lagos, and a ship was dispatched to tow them into port.
Aftermath and Significance
The operation was a resounding success. The commandos managed to tow the ships to Lagos, Nigeria, without encountering significant resistance from Axis forces or interference from neutral observers. The capture of these ships deprived the Axis of valuable resources and demonstrated the effectiveness of the SOE and the SSRF in executing daring operations.
Operation Postmaster had several significant outcomes.
