 The attack was planned to proceed in three phases. The initial assault would be carried out by the 56th British Infantry Brigade who would cross the IJssel at night in Buffalo IVs of The Ontario Regiment before clearing the eastern and southern districts of the city. In phase two, the 146th British Infantry Brigade would move forward and attack the high ground north of Arnhem. In the third phase, the 147th British Infantry Brigade would advance through 56th's positions and secure the high ground and north bank of the Nederrijn west of the city. With the heights around Arnhem secure the 5th Canadian Armoured Division would advance through the city and I Corps would resume its advance west. The British took several Canadian units under command along with Churchill Crocodile tanks of the 79th British Armoured Division. Most of the 1st Canadian Infantry Division and 5th Canadian Armoured Division were placed in support, and a composite group known as Murphyforce provided a diversion south of the Nederrijn.
