In the opening of Operation VERITABLE (8 February 1945), 15th (Scottish), operating as part of Lieutenant-General Brian Horrocks' XXX Corps, had the task of breaching the northern extension of the Siegfried Line, consisting of anti-tank ditches, minefields, concrete emplacements and barbed-wire entanglements, and then seizing the key ground around Cleve. The division led with 46th (Highland) Brigade on the right and 227th (Highland) on the left. The opening phase went well, the troops having more difficulties with mud and mines than with the enemy. By dark, 227th Brigade had captured Kranenburg. But the follow-up attack by 44th (Lowland) Brigade, carried on tanks and in Kangaroo APCs, and preceded by flail and bridging tanks, was held up on the rough tracks. However, Horrocks heard that the Scots were entering Cleve, so he launched 43rd (Wessex) Division to pass through 15th (Scottish). He afterwards referred to this as "one of the worst mistakes I made in the war..." 15th (Scottish) had not got as far as reported, and the arrival of 43rd caused "one of the worst traffic jams of the whole war ... The language heard that night has seldom if ever been equalled."
