On the 11th November, the 1st Cavalry Division was on the Fifth Army front, and its leading troops reached a line north of Mons and about nine miles east of Ath. The division was withdrawn on the 12th, and concentrated near Peruwelz (north of Conde). On the 16th November, orders were issued that the division would lead and cover the advance of the Second Army into Germany, and the forward march was begun the next day. Moving through Namur (22nd), the division crossed the German frontier on the 1st December, the 1st Cav. Bde. covering the advance of the Canadian Corps and the rest of the division leading the march of the II. Corps. On the 6th December, the 2nd Cav. Bde. pushed on, reached Cologne, and secured the bridges over the Rhine, and on the next day the 1st and 9th Cav. Bdes. also reached the Rhine, south and north of Cologne respectively. On the 12th December the division (less 1st Cav. Bde.) crossed the Rhine by the Hohenzollern Bridge, whilst the 1st Cav. Bde. crossed at Bonn; and on the 13th December the brigades moved forward to their final positions on the perimeter of the bridgehead. The advance into Germany was over.
