 A new forward headquarters, Alsos Forward North (AFwdN), was opened at Aachen, and on 8 February the Alsos Mission reopened its forward headquarters in Strasbourg as Alsos Forward South (AFwdS). In March, the U.S. Twelfth Army Group launched Operation Lumberjack, an offensive to clear the Germans west of the Rhine. Pash, who was promoted to colonel on 6 March, led an Alsos Mission detachment into Cologne on 7 March, but little additional information was found.
