Operation Anglo

Operation Anglo was a 1943 Allied special forces raid on Axis shipping and installations in the Aegean Sea during World War II. Conducted by small teams from the Special Boat Section (SBS) and operatives linked to the Special Air Service, the raid targeted vessels and infrastructure around the island of Kastellorizo and nearby islets. The action combined clandestine insertion, demolition, and guerrilla-style evasion against Italian Empire naval assets amid shifting strategic competition in the eastern Mediterranean.

Background

In early 1943 the Mediterranean theatre saw intense naval and air activity shaped by outcomes of the North African campaign and the ongoing struggle for control of sea lanes. The island group around Kastellorizo provided anchorage and staging for the Regia Marina and Axis supply convoys supporting operations in the Dodecanese campaign theatre. British planners in Middle East Command and Combined Operations Headquarters sought to interdict Axis coastal shipping and gather intelligence ahead of larger operations such as the planned Sicily invasion (Operation Husky). Small-unit raids had precedents in operations like Operation Postmaster and Operation Anglo drew on lessons from SAS and SBS actions in the North African campaign and Special Operations Executive missions in occupied Greece.

Planning and training

Planning for the raid was developed by officers experienced in clandestine operations in the eastern Mediterranean. Officers linked to Special Boat Section and Special Air Service planned a surprise landing using collapsible canoes and small craft to place explosive charges on anchored Axis vessels. Training emphasized paddle craft handling, covert approach at night, demolition with limpet mines and detachable charges, and escape through rugged terrain to rendezvous points. The operation integrated local knowledge from sympathetic Greek islanders and intelligence from agents connected to Special Operations Executive networks operating in the Aegean islands. Command elements coordinated with regional commands in Cairo and naval units from Mediterranean Fleet for insertion and extraction windows timed with tidal and moon phases.

The raid

A small team of operatives made a nocturnal approach to target anchorages around Kastellorizo using folding craft launched from a submarine or covert launch point. Under cover of darkness the raiders paddled to several moored merchant ships and auxiliary warships, attaching explosive charges to hulls and scuttling equipment where possible. Despite vigilant sentries and coastal defenses, the teams managed to sabotage multiple Axis vessels, triggering fires and explosions that damaged or destroyed tonnage supporting regional logistics. The raid exemplified tactics refined in earlier operations such as Operation Frankton, using stealth insertion, limpet mines, and rapid withdrawal over difficult terrain. Enemy reaction involved searches by Regia Marina patrols and aerial reconnaissance from bases in the Dodecanese, while occupying garrison units attempted to intercept escaping operatives.

Aftermath and casualties

Following the demolition, Allied evacuation plans were complicated by increased Axis patrols and a lack of immediate extraction due to submarine availability and shifting operational priorities after the Allied invasion of Sicily. Some raiders evaded capture, aided by island residents and clandestine sympathizers committed to anti-Axis resistance, including contacts within networks associated with Greek Resistance groups. Several operatives were captured or killed during the withdrawal or in subsequent actions; Axis losses included sunk or damaged merchant and auxiliary vessels belonging to the Regia Marina logistics chain. The operation had tactical impact by temporarily disrupting convoy movements and denying the enemy safe anchorage, contributing to the broader interdiction campaign across the Aegean Sea in 1943. Casualties and prisoners were notable among a small force, reflecting the high-risk profile of small-unit maritime sabotage missions previously seen in operations such as Operation Jaywick and Operation Rimau.

Commemoration and legacy

Operation Anglo became part of the narrative of elite British special forces' exploits in the Mediterranean campaign, influencing postwar histories of Special Boat Service and Special Air Service operations. Personal accounts, memoirs, and later historical studies placed the raid alongside better-known actions like Operation Frankton, shaping public perceptions of clandestine warfare. Monuments and local commemorations on islands in the eastern Mediterranean mark cooperation between Allied operatives and Greek islanders, and scholarly works examine the raid's role in logistical attrition against the Axis maritime effort. The raid’s techniques informed subsequent maritime sabotage doctrine within the Special Operations Executive and postwar special forces development in the United Kingdom and allied services.
