During World War II, the deployment of ML 1050 to Freetown, Sierra Leone was dictated by Freetown’s status as one of the most critical Allied naval bases in the world. It served as the primary assembly point for the South Atlantic convoy system.
Built by McGruer & Co. in Scotland, ML 1050 arrived in West Africa in early January 1942. Because Harbour Defence Motor Launches (HDMLs) were small, 72-foot wooden vessels with a top speed of only 11 knots, they could not cross the Atlantic on their own power. Instead, she was "freighted" (shipped as cargo) from the River Clyde across the Atlantic on a larger transport merchant vessel.
Once unloaded at Freetown, she became an active operational unit of the 108th Motor Launch Flotilla, working alongside sister ships ML 1044, ML 1065, and ML 1066.
Operational Logistics & Routine
The 108th Flotilla operated under the West Africa Command. Due to the tropical environment, crew fatigue, and the maintenance needs of wooden-hulled diesel craft, the flotilla frequently rotated its launches between Freetown and secondary regional bases like Bathurst (now Banjul, The Gambia), Dakar, and Port Etienne.
The primary operational duties of ML 1050 during this West African tenure focused heavily on the following areas:
1. Close-Shore Convoy Escorts
While larger corvettes and destroyers protected deep-ocean convoys, ML 1050 and her sister ships took over the hazardous job of escorting regional, slow-moving merchant vessels navigating the West African coastline. Records of the 108th Flotilla show these launches routinely escorted specific merchant ships (such as the SS Mary Kingsley and SS Alsace) between localized ports to feed into the larger SL (Sierra Leone) convoy chains heading toward the UK.
2. Inner-Harbour Anti-Submarine Sweeps
Freetown's massive natural harbor routinely held dozens of anchored merchantmen waiting for escorts. German U-boats frequently stalked the approaches to the harbor. Armed with a 3-pounder main gun, machine guns, and depth charges, ML 1050 conducted around-the-clock anti-submarine sweeps across the harbor entrances. Utilizing her basic ASDIC (sonar) gear, her job was to detect and deter any U-boats attempting to slip into the anchorage or fire torpedoes from the harbor mouth.
3. Coastal Patrol and Sea-Rescue Support
Small motor launches in the West Africa Command also acted as a vital safety net for Allied air operations. The Royal Navy and RAF operated flying boats (like the Short Sunderland) out of the region to spot submarines. ML 1050's flotilla was frequently ordered to sea on short notice to hunt down reported enemy sightings or recover downed Allied aircrews out of coastal waters.
ML 1050 maintained this defensive operational rhythm protecting the West African trade routes until she was recalled to the United Kingdom to undergo retrofitting for her next major historical role: the 1044 D-Day landings in Normandie.
