After entering service, HMIS Sutlej moved straight into Irish Sea convoy work and then joined the escort of convoy WS11. The formation included the battlecruiser HMS Repulse, destroyers, cutters, and the armed merchant cruiser HMS Derbyshire, illustrating how a troop convoy could combine ships with very different capabilities. When WS11 divided, Sutlej and HMS Totland took the slow section to Freetown before she rejoined the onward escort into the Indian Ocean. In September 1941 she was assigned to the Mediterranean Fleet for anti-aircraft defence of convoys and other formations. Her early itinerary demonstrates the geographic reach expected of a Royal Indian Navy sloop and the flexible division of escort forces around convoy speed.

Sutlej’s work with convoy WS11 shows how a Royal Indian Navy sloop moved between local escort duty, a mixed troop-convoy screen, and wider fleet service.
