Hi Bob;
You asked:
'there was no instance during the Italian campaign in which Canadian troops were carried in or operated alongside 'Roo-borne infantry.' , the answer to this is two fold, first, your right there was no instance during the Italian Campaign when Canadian troops were carried in, or operated Kangaroos.
There was only one instance where there was Kangaroo borne Infantry involved anywhere near Canadian operations, and this occured during the clearing of the Granarolo Salient (3-5 Jan 45), when on 4 Jan 45, a British Kangaroo borne Battalion, was involved in the crossing of the Naviglio Canal, by elements of the British 56th Infantry Division, to the left of the Canadians (see attached map).
Hope this answers your questions Bob.
Cheers
