Input: Question: Did the Battle of Hurtgen Forest overlap with the action in the Scheldt Estuary? Passage:Joining the Battle of Hürtgen Forest, the division moved into defensive positions in the vicinity of Wuustwezel, Belgium on 23 October 1944. The Timberwolves were then assigned to British Field Marshal Bernard Montgomery's Anglo-Canadian 21st Army Group under the British I Corps, along with the U.S. 7th Armored Division, in order to clear out the Scheldt Estuary and open the port of Antwerp. While the U.S. 7th Armored Division was assigned static duty holding the right flank of the gains made during the failed Market Garden operation, the 104th Infantry Division was to assist the First Canadian Army in the taking of the Scheldt. The Timberwolves travelled across France by train and debarked near the Belgian-Dutch border and waited for word to take part in a new allied offensive, Operation Pheasant, taking the place of the experienced British 49th Infantry Division on the left flank and the Polish 1st Armored Division on the right.
