Dobie selected a location on the river near Renkum to make the crossing of the Rhine (codenamed Digby). The Rhine was 150 to 200 meters wide. A route to the river from the north were decided upon, and it was arranged that the men would be met on the north bank by Royal Canadian Engineers and British Royal Engineers of XXX Corps escorted by men of the 506 PIR, 101st Airborne Division. To help guide the evaders the crossing point would be marked by tracer fire from a Bofors Gun. The American forces sent patrols north of the river and tracer fire over the river for several nights to disguise the actual purpose of the operation when it came. The date was set for the night of 23–24 October.
