'Grönland' was a U-boat wolfpack operation in the Atlantic (10/27 August 1941).

The wolfpack comprised U-38, U-43, U-71, U-73, U-77, U-82, U-84, U-96, U-101, U-105, U-129, U-202, U-206, U-501, U-553, U-563, U-567, U-568, U-569, U-652 and U-751, and for the loss of none of its own number sank the Canadian corvette Picotee, which was one of the ON.4 convoy’s 21 escorts and succumbed to a torpedo from Kapitänleutnant Joachim Preuss’s U-568, and damaged the 10,917-ton British auxiliary minelayer Southern Prince.

Two of the wolfpack’s boats, Oberleutnant Heinrich Schuch’s U-38 and Kapitänleutnant Hans-Heinz Linder’s U-202, also sank two independent vessels (1,700-ton Panamanian freighter Longtaker and 230-ton British trawler Ladylove respectively).
