The 2nd Escort Group (2 EG) was a British anti-submarine formation of the Royal Navy which saw action during the Second World War, principally in the Battle of the Atlantic.
2 EG was formed in April 1943, one of five such support groups formed at the crisis point of the campaign. It was to act as reinforcement to convoys under attack, with the capacity to actively hunt and destroy U-boats, rather than be restricted to escort duties. Comprising six sloops of the Black Swan-class, the group was led by Captain F.J. "Johnnie" Walker, Britain's most successful anti-submarine warfare commander, in Starling. The combination of an active hunting group and a charismatic, determined and innovative anti-submarine specialist such as Walker proved to be a potent force; 2 SG was the most successful anti-submarine unit of the war, being credited with the destruction of 23 U-boats during two years of active service.
Officially called 2nd Escort Group, (more commonly referred as the 2 SG) was formed in April 1943, one of five such groups. Its purpose was to provide reinforcement to convoys at sea, being equipped to spend extended periods at sea moving from one convoy to another as needed. Its function primarily was to assist a convoys escort in its defence, though it also had the facility to spend time, which escorts did not have, to continue attacks on U-boats to successful conclusion rather than having to break off to maintain the guard on the convoy.
Walker however was determined that the group would be active in destroying U-boats and impressed this aim on his commanders from the outset.
The group comprised six sloops of the Black Swan class, making it a highly uniform group, and the sloop design was well suited to the task, with good endurance, adequate speed and specialized anti-submarine armament. In addition Walker had developed a range of A/S tactics, which 2 SG became adept at, such as the "creeping attack" and the "barrage attack".
