The 17th Duke of York's Royal Canadian Hussars (7th Reconnaissance Regiment, 7th RECCE) war diary reports on October 26, 1944: "A" Squadron using the Assault Troop was to proceed from grid line (00) towards Oostburg, Netherlands and "B" Squadron using 2 Troops were to proceed from Oostburg in a south westerly direction and join up with "A". "A" Squadron was able to do their task without too much difficulty and soon reached the site where the bridge was to be erected. "B" Squadron on the other hand had to cross a river over a foot bridge and continue to "C" Squadron where they were lent vehicles to enable them to maintain communications. Their first job was to remove a road block at "C" Squadron and the Queen's Own Rifles junction point 042107 (Bakkersstraat and Nieuveltweg, Oostburg). As this was being removed, Capt Whittingham's vehicle, a light Scout car, ran over a mine and he was blasted completely out of the car. A second mine exploded and turned the car over on him. He was killed instantly. Captain J.O. MacArthur was immediately sent to take command and proceeded down the main road towards "A" Squadron meeting heavy opposition in the way of mines, booby traps and enemy mortar and shell fire. He eventually linked up with "A" Squadron at last light. The number of PW's (German war prisoners) taken was 22. One 37mm gun was destroyed.
