 commander, in . 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.

Formation

Officially called 2nd Escort Group
Escort Group (naval)
Escort Groups for convoy protection were a British development in the war at sea during World War II. They were a tactical innovation by the Royal Navy in anti-submarine warfare, to combat the threat of the German Navy's "wolfpack" tactics....

, (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

".

The group originally comprised: (Capt. F.J. Walker), (Cdr. R.M. Aubrey), (Lt.Cdr. R.E.S. Hugonin), (Lt.Cdr. F.B. Proudfoot), (Lt.Cdr. D.E.G. Wemyss), (Lt.Cdr. W.F. Segrave)

During April the group was engaged in working up and training; Starling, Wild Goose and Kite were new ships, and none had worked together before. Under Walkers training (previously the Experimental Commander at HMS Osprey, the RN Anti-submarine training school) the group became a highly effective and successful unit.

First patrols

The group's first patrol in May 1943 was uneventful. There were several major convoy battles during the month, but none involving 2 SG. The group operated in support of HX 235 and ONS 8, sailing ahead in an attempt to encounter and breach any U-boat patrol lines drawn across the convoy routes.

The group's first success came in June. Its first U-boat was detected on 1 June 1943: fortuitously on a fine day, and identified by a Lt. Earl Howe Pitt, the event was dubbed another "Glorious First of June

" by Walker. Over a 15-hour period the group found, tracked and destroyed , in the longest hunt of the Atlantic campaign up to that point, and a vindication of the support group ethos, leaving ships free of escort responsibilities to destroy U-boats.

Bay offensive

After a refit at Liverpool, after which Cygnet departed to another group, 2SG was assigned to "Operation Musketry", an attempt in concert with Coastal Command to interdict the U-boat transit routes across the Bay of Biscay

. On 24 June 1943 the group was successful in destroying and , though Starling was damaged in the process of ramming U-119 and was forced to retire. Walker elected to stay with the group, exchanging commands with Wild Goose, and, after the group returned to port, with Kite. 2 SG was joined at this point by (Lt.Cdr C. Gwinner), as replacement for the damaged Starling.

On 30 July 1943 Walker's group saw further success when they encountered a group of three U-boats on the surface (two were vital submarine type XIV

 aircraft.

But whilst the remainder of the operation saw the destruction of 20 U-boats over a nine-week period, 2 SG's time was unproductive, and no further successes were recorded.

Atlantic operations

In September 1943, after a further refit, 2 SG went to the North Atlantic, in company of the escort carrier . The group was joined by (Lt.Cdr R.S. Abrams), while Woodpecker was in for repairs.

. No successes were recorded, though the convoy battle saw three U-boats destroyed, with no ships lost.

However in November 1943, in operations around HX 264, 2 SG accounted for two more U-boats, and . Whilst the United States Navy had had much success using carrier groups in a hunter killer role on the mid-Atlantic route, the Royal Navy's experience was less positive. Winter gales made flying difficult and hazardous, while the need to provide protection to the carrier hampered A/S operations. 2 SG at least generally had more success operating without carrier assistance.

On December 2 SG was acting in support of SL 140/MKS 31 with 4 SG (Cdr. E.H. Chavasse). 2 SG put in a determined attack on a U-boat, (thought to be ), but was unsuccessful, though the battle for SL 140/MKS 31 saw the destruction of a U-boat, without loss of ships.

Six in one trip

In January 1944 2 SG sailed on its most famous exploit, accounting for six U-boats in one patrol, three of them in one 15-hour period.

On 31 January 1944 Walker's group gained their first kill of the year when they sank . On 9 February his group sank , , and in one action, then sank on 11 February, and on 19 February. This patrol was ended on 20 February 1944, when one of Walker's group, , was torpedoed (possibly by or by ). After an 8-day struggle to get her home, Woodpecker sank in a gale off the Scillies; all of her crew were saved. Woodpecker was the only ship of 2 SG lost in action.

 was present to greet Walker and his ships. Walker was promoted to Captain and awarded a second Bar to his DSO.

Arctic convoy

In March 1944 the group returned to North Atlantic, destroying on weather patrol, before joining Arctic convoy JW 58. It was joined in this for a short period by . 2 SG met and destroyed in transit across the "Rosegarden", but had no other success, though three U-boats were destroyed in attacks on JW 58. The return convoy, RA 58, was also attacked but neither side saw any success.

In May 1944, 2 SG responded to an attack on by . Though starting from 300 miles away Walker, in an inspired piece of work, divined where to search and after a three-day search gained contact. An 18-hour hunt brought U-473 to the surface, where she was sunk by gunfire.

In June 1944, 2 SG was joined by , , and , replacements for Kite and Magpie. That month the group was on search and destroy operations in the South-Western Approaches, as part of "Operation Neptune

Later operations

In July 1944, 2 SG was back in action, led initially by Dominica (Cdr. N.A. Duck) and later by Wild Goose (Cdr. D.E.G. Wemyss).

The group had one successful patrol during August operating in the Bay of Biscay.
Four U-boats, , , , and were accounted for while attempting to cross the bay to and from their bases.

The months following this were unfruitful, however, as the U-boat Arm changed its tactics to operate in the shallow inland waters around Britain, using the schnorkel

to remain submerged for entire patrols. This created a different set of tactical problems, requiring different tactics of the escorts.

Last successes

In 1945 Loch Fada and Loch Killin were transferred, to be replaced by , , and .

As 2 SG grappled with the changed nature of the campaign the group saw its last successes. In February 1945 the group destroyed two more U-boats, and (some sources say this was ).

2 SG was also credited with , bringing its score to 23. Wemyss reports the attack, in March 1945, but after a report of another sinking in the same area six months earlier, concluded they were "flogging a dead horse".

However a post-war report of U-683 missing in the area led to 2 SG being credited with her destruction. More recent analysis has questioned this, and the assessment was changed in 1989. It is now thought that 2 SG's attack was on the wreck of , sunk in September 1944.

Despite this, 2nd Support Group was responsible for the confirmed destruction of 22 U-boats during World War II, making it the most successful anti-submarine unit of the entire conflict.
