The battle around convoys HX 229 and SC 122 occurred during March 1943 in the Battle of the Atlantic, and was the largest convoy battle of World War II. British merchant shipping was formed into convoys for protection against German submarine attack. Kriegsmarine tactics against convoys employed multiple-submarine wolfpack tactics in nearly simultaneous surface attacks at night. Patrolling aircraft restricted the ability of submarines to converge on convoys during daylight. The North Atlantic winters offered the longest periods of darkness to conceal surfaced submarine operations. The winter of 1942–43 saw the largest number of submarines deployed to the mid-Atlantic before comprehensive anti-submarine aircraft patrols could be extended into that area. During March, there was a series of fierce convoy battles which became, for the Allies, the crisis point of the whole campaign. One hundred merchant ships in trade convoys HX 229 and SC 122 encountered three wolfpacks of 38 submarines in a single sprawling action, which German radio reported as "the greatest convoy battle of all time" (Die grösste Geleitzugschlacht aller Zeiten).Middlebrook p.276 A Royal Navy report later concluded "The Germans never came so near to disrupting communications between the New World and the Old as in the first 20 days of March 1943".Roskill p367.

The Strait of Belle Isle (détroit de Belle Isle (Beautiful Island)), sometimes referred to as Straits of Belle Isle or Labrador Straits) is a waterway in eastern Canada that separates the Labrador Peninsula from the island of Newfoundland, in the province of Newfoundland and Labrador. The strait is approximately 125 kilometres long and ranges from a maximum width of 60 km to just 15 km at it narrowest, the average width being 18 km. Navigation in the strait can be extremely hazardous with strong tidal currents interacting with the Labrador Current, depths reaching several hundred metres in places, sea ice for 8–10 months of the year, and variable weather conditions including gales and fog. The strait is the northern outlet for the Gulf of Saint Lawrence, the other two being the Cabot Strait and Strait of Canso. As such, it is also considered part of the Great Lakes-St. Lawrence Seaway system. While sea ice prevents year-round shipping, the Canadian Coast Guard maintains a vessel traffic service (VTS) to ensure collisions do not occur. The name is derived from Belle Isle (Beautiful Island), located at the extreme eastern end of the strait and roughly equidistant between Table Head, Labrador, and Cape Bauld, Newfoundland. A seasonal ferry service (April through January) operates at the western part of strait between St. Barbe, Newfoundland, and Blanc Sablon, Quebec. New road construction for the Trans-Labrador Highway resulted in the removal of ferry services to outports in the northeastern part of the strait in 2002. The idea of building a fixed link across the strait between Labrador and Newfoundland, known as the Newfoundland-Labrador fixed link, has been raised numerous times in recent decades following an unsuccessful attempt to build a tunnel carrying electrical wires in the mid-1970s. If such a link were built, it would likely be a 17-km-long submerged rail tunnel. The proposal is meant to reduce the province's reliance upon the Marine Atlantic ferry service to Nova Scotia, but the project's high costs and lack of suitable road network between Labrador and Quebec have been cited as major obstacles. The October 2003 provincial election resulted in the newly-elected Progressive Conservative government announcing joint federal-provincial funding for a study of the concept. A 35 km submarine cable across the strait is under construction as part of the Lower Churchill Project.
