After the winding down of the battles of 1917, the Scots Greys found themselves near the St. Quentin canal. There, they witnessed the German offensive forcing their way across the canal. Although the Scots Greys held their positions, they were soon in danger of being flanked. After almost three years of static warfare, the rapidity of the German advance caught the regiment flat flooted as the German attacks penetrated the Scots Greys position. In the confusion of the retreat, detachments of the Scots Greys became lost and ended up serving with other regiments of the 5th Cavalry Brigade, fighting rearguard actions as the B.E.F. retreated. Once the Michael Offensive began to grind down in April, the Scots Greys, along with the other cavalry regiments, were able to be withdrawn from the line to refit and reorganise.
