On 24 September 1944, the frigate HMCS Swansea (foreground) rescued seven British soldiers from a sinking segment of an artificial harbour (right).

Towed by a tug, this giant floating concrete structure, called a Phoenix, was headed to Normandy to help create an artificial harbour known as a "Mulberry". Soldiers were stationed on board to supervise the towing and operate pumps to keep it afloat. Swansea, called to assist when heavy weather interfered with the towing and caused the Phoenix to start sinking, made several attempts to rescue the soldiers (right, on Phoenix). It ultimately succeeded, after coming dangerously close to the sinking concrete structure.
