SC 143 was a North Atlantic convoy of the SC series which ran during the battle of the Atlantic in World War II. It was the second battle in the Kriegsmarine's autumn offensive in the North Atlantic.
Following the attack on convoys ONS 18 and ON 202 by the wolfpack Leuthen, U-boat Control (Befehlshaber der Unterseeboote (BdU) was convinced of success and eager to continue the offensive. Accordingly, they re-organized the boats then in the North Atlantic into a new patrol line, the 12 remaining Leuthen boats being joined by 9 new-comers, from bases in France and Germany. Code-named Rossbach, the group was stationed at the western edge of the Greenland Air Gap to intercept the expected east-bound convoys, carrying materiel for the invasion of Europe.
