Convoy ON 92 was a tradeconvoy ofmerchant ships during theSecond World War. It was the 92nd of the numbered series ofON convoysOutbound from the British Isles toNorth America. The ships departed fromLiverpool on 6 May 1942[1] and were joined on 7 May[2] byMid-Ocean Escort Force Group A-3.
The convoy was discovered byWolfpack Hecht on 11 May; seven ships were sunk before theU-boats lost contact with the convoy on 13 May.[3] Surviving ships reachedHalifax, Nova Scotia on 21 May.[1]
ON 92 was a west-bound convoy of 42 ships, eitherin ballast or carrying trade goods, and sailed fromLiverpool on 6 May 1942 bound for ports in North America. The convoy commodore was Capt. R Gill inSouthern Princess.
It was escorted bymid-ocean escort group A-3, comprising theUnited States NavydestroyerGleaves (Capt. J Heffernan as Senior Officer Escort), theUnited States Coast GuardcutterSpencer, and fourRoyal Canadian NavycorvettesAlgoma,Arvida,Bittersweet andShediac. The convoy was supported by a rescue ship, theNorth SeapacketBury.[4] Two of the merchant ships were equipped asCAM ships, with a catapult-launchedHurricane fighter as temporary air cover. Heffernan had a background in destroyers andanti-submarine warfare but was inexperienced in convoy protection, as was his group. OnlyBittersweet had the new 10 cm radar, and only the rescue shipBury hadHF/DF.[5][6]
ON 92's passage was barred by the patrol group "Hecht", comprising sixType VII U-boats. Of these two commanders were experiencedKnight's Cross holders, while the others were on their first Atlantic patrol.[5]
After making rendezvous with its ocean escort ON 92 proceeded west, following along the great circle route to reduce distance. However German intelligence (B-Dienst) was aware of its passage, andU-boat Command (BdU) was able to send group "Hecht" in pursuit.On the morning of 11 MayU-569 made contact and began to shadow. Its transmissions were detected byBury, which was confirmed by theAdmiralty that afternoon but Heffernan made no response until 1700, when he ledGleaves andSpencer in a wide sweep around the convoy. At 1749Gleaves sighted aU-boat 17 miles (27 km) ahead and both proceeded to attack, continuing until after midnight.[7] Meanwhile, two more U-boats were in contact,U-94 andU-124, both commanded by Knights Cross holders. After sunset the commodore ordered evasive maneuvers, but without success, and at 2300U-124 attacked, sinkingEmpire Dell and damagingLlanover.[8] A second attack byU-124 hitMount Parnes andCristales, whileU-94 hitCocles.Algoma sighted one and counter-attacked but with no success. At this pointGleaves andSpencer rejoined the convoy and no more attacks developed.Arvida andShediac were able to pick up survivors, withBury.[9]
On 12 May the three U-boats in contact were joined by three more "Hecht" boats,U-96,U-406 andU-590, and all six continued to shadow. At 1300 Heffernan again detachedGleaves andSpencer in a sweep around the convoy; at 1943Spencer sighted two U-boats 27 miles (43 km) northwest of the convoy, and engaged with gunfire, while at the same timeGleaves made asonar contact 18 miles (29 km) southeast and again began an anti-submarine hunt.
At 2253 the U-boats around the convoy attacked again,U-94 hittingBatna. She was counter-attacked byBittersweet, but escaped. Both ships firedstar shell, which broughtGleaves andSpencer back to the convoy. At 0310 on 13 MayU-94 had a final success, hittingTolken, but was driven off by defensive gunfire from the merchant. At this point foul weather closed in and the pack lost contact.
No further attacks developed and on 13 MayBury, with 178 survivors on board, was detached toSt Johns, escorted byArvida.[10] The convoy was joined by units of Western Local Escort Force on 17 May and made port atHalifax on 21 May.[5]
ON 92 lost seven ships of a total of 42 that set out. The Admiralty andWestern Approaches Command (WAC) were unimpressed with Heffernan's performance, particularly as he described it in his report as a success, commenting "all escorts are entitled to credit for a highly satisfactory performance." WAC disagreed, feeling the group had "failed lamentably" in its defence of ON 92. The commodores report sums up the episode by commenting "Gleaves was never there when ON 92 was attacked."[10] After this Heffernan was moved to other duties, with leadership of A-3 being passed to USCG commander P Heineman of the cutterCampbell.[5]
BdU had reason to be pleased with the sinking of seven merchant ships from the convoy, although this was the only successful attack on any North Atlantic convoy in the month of May. It was also noticeable that the only success fell to the two experienced commanders; the other four "Hecht" skippers achieved nothing.[11]
