Churchill.

From a comment to that previous blog entry regarding the U-1226:

"NOTHING TO DO WITH HUDSON'S BAY"

"It must be precised that the Churchill River (Formerly Hamilton) flows out directly in the North Atlantic, off the Coast of Labrador and well above the Island of Newfoundland."

"As for Hudson's Bay it is way off to the West and inland, bordered to the East by Province of Quebec and to the West by Ontario, Manitoba an the newly created Nunavik Territory. JAM Bornais"

Bert stands corrected most decidedly so and thank you Anonymous.

There is a Churchill River flowing into the Atlantic. 

"The Churchill River . . . is a river in Newfoundland and Labrador which flows east from the Smallwood Reservoir in Labrador into the Atlantic Ocean via Lake Melville. The river is 856 km (532 mi) long and drains an area of 79,800 km2 (30,800 sq mi); it is the longest river in the province. It was named Hamilton River until 1965."

AND there is a Churchill River flowing into Hudson Bay.

"The Churchill River . . .  is a major river in Alberta, Saskatchewan and Manitoba, Canada. From the head of the Churchill Lake it is 1,609 km long. It was named after John Churchill, 1st Duke of Marlborough and governor of the Hudson's Bay Company from 1685 to 1691."

That submarine the U-1226 evidently found in the Churchill River [Atlantic] and not the Churchill River [Hudson Bay].

Confirmation awaits but this is more or less a certainty, and makes a lot more sense and is more plausible too.
