Convoy ON 166 Cruising Order
Departed Liverpool at 13:30 on Febr. 11-1943 and arrived New York on March 3 (Arnold Hague says 48 ships).
Transcribed from several documents received from Roger Griffiths, England (his source: Public Records Office, Kew).

Info on ships sunk has been added with the help of
"The World's Merchant Fleets", R. W. Jordan
"Axis Submarine Successes of World War Two", Jürgen Rohwer, and
"The Allied Convoy System", Arnold Hague.

Please note that there were more ships in this convoy than those listed in this table. The A 1 form appears to show only the ships that made it to New York; stragglers and ships sunk are not included in the document. See also Convoy ON 166 in the section listing ships in all ON convoys.
Where stations of ships sunk are known, I've added them to these columns, but not all stations are known - a complete list of ships sunk, including the Rescue Vessel Stockport, can be found in Notes below.
After ships had gone down (or straggled), other vessels took their stations in the convoy, as noted in this table.

Br=British, Norw=Norwegian, Pa=Panamanian, Am=American, Du=Dutch

For info, some of the ships in this convoy are also mentioned in the eastbound Convoys HX 222, HX 223 HX 224 (see also HX 229A and other eastbound convoys from this time period).

†=died (sources don't always agree on the number of casualties, hence my question marks), dam=damaged

Markay (Am?) and the Panamanian El Coston joined from Iceland on Febr. 16 in 57 10N 18 10W - El Coston was detached at 17:00 on the same day (57 12N 18 30W) to return to Iceland with leaky condensor and shortage of water.

Empire Cavalier joined from Halifax at 10:00 on Febr. 28 in 42 44N 59 24W.

Commodore W. E. B. Magee, D.S.O., R.N.R. was in City of Canberra, Vice Commodore was the captain of Lochmonar.

The Milford Haven portion, consisting of 18 ships, sailed at 14:00 on Febr. 10 with Commander A. MacKellar R.D. R.N.R. acting as Commodore in Tortuguero, Vice Commodore being the captain of Empire Trader. The Dutch Madoera is also mentioned in this portion, which was escorted by HMS Rosemary (should this be the trawler Lady Rosemary?) and HMS Cotillion + 1 more unnamed trawler. Madoera is said to have been sent to Belfast at full speed, having been unable to keep up with the speed (average speed of this portion is given as 9.6 knots) - must have joined up with ON 166 from Belfast later(?).

Average speed of Convoy ON 166: 7.2 knots. (Daily positions of convoy at 08:00 are available on request via the contact address provided at the bottom of this page).

Heavy weather reaching gale force was encountered for the first 8 days of the voyage. Commodore Magee says: "I am happy to report the excellent behaviour and steadiness of the convoy under difficult and trying conditions particularly during enemy attacks".

Stragglers (note that some of these are not included in the table above):
Polish Lechistan during the night of Febr. 20 in 53 28N 25 46W.
Norwegian Stigstad dropped out during the night of Febr. 21 in approx. 51 10N 27 55W.
Rescue Vessel Stockport* after night of Febr. 21 in approx. 48 30N 30 10W.
Markay "broke convoy without permission at 22:45 on Febr. 23 in 45 49N 39 07W"
Jonathan Sturges and Madoera during the night of Febr. 24 in 45 06N 39 14W.
Gyda was in collision with Fort Thompson at 19:45 on Febr. 24, not seen since.
American Charles H. Cramp during night of March 1.
The British Amastra was unable to maintain 9 1/2 knots in fine weather.

* The Rescue Vessel Stockport was on her 8th voyage as such, having started out from Clyde Febr. 11. She was sunk on Febr. 22 with the loss of 63 men. Arnold Hague states in his "Convoy Rescue Ships 1940-1945" that she had stood by a number of torpedoed ships and had rescued 91 survivors, but while trying to rejoin the convoy she disappeared without further signal or any positive identification of an attack in German records. He adds: "From an analysis of various German reports obtained in 1945 the loss can be attributed to U-604, even though her Captain's description of his target, as seen at night, is dubious. There are no other reported attacks however which could fit the loss of Stockport".
Jürgen Rohwer also lists U-604 as the culprit, giving the date as Febr. 23 (at 03:12 German time), adding in a footnote: "The Stockport had fallen behind the convoy after rescuing survivors from the Empire Trader at 01:00 hrs GCT on 22.02.43".

The following ships were also sunk or damaged - more details on each of them are available at the external links at the end of this text:
