HMCS Moncton (K139) - Wartime Service

Wartime Service

Following her commissioning, Moncton sailed to Halifax and was assigned to Atlantic Coast Command (AT) but unallocated as she was fitting out and performing sea trials for the remainder of April. In May she began work-ups with her new crew out of Halifax and she joined the RCN's Atlantic Fleet on 12 May 1942. Another highlight for Moncton in 1942 was conducting training with (an as yet anonymous) British submarine off Halifax.

From June 1942 to June 1943, Moncton was tasked to Western Local Escort Force (WLEF) for convoy escort operations. During her assignment to WLEF, Moncton participated in the escort of the following convoys

In June 1943, WLEF was divided into separate escort groups and Moncton was tasked to EG W5 (HQ in Halifax) during June–July. Moncton collided with merchant Jamaica Producer on 28 July 1943. From August–September 1943 Moncton underwent repairs at Dartmouth Marine Slips, Dartmouth. She returned to EG W5 and operated in convoy escort operations from October–December.

Moncton was transferred to the RCN's Pacific Fleet in January 1944 and departed for Esquimalt, via Guantanamo Bay, Cristóbal, Balboa and San Pedro.

Upon her arrival, she was tasked to the Esquimalt Force (unallocated) and underwent an extensive refit at Vancouver from 5 May - 7 July 1944 where her forecastle was extended and she was brought into line with the modified Flower-class design. From July 1944 to December 1945 she was tasked to Pacific Coast Command (unallocated).

Following V-J Day, she was placed in reserve status at Esquimalt and decommissioned from the RCN on 12 December 1945, the last of the first batch of Flower class corvettes to serve the Navy as an active warship.
