it has alot of pictures, and some information about canada before d-day (dieppe and such)
canadian forces reached their objectives on d-day (no other beaches managed this) and even went past the objectives as payback for dieppe. the DD tanks also made it to shore which was a big help, the american ones hit bad currents and capsized.
whats the plan for the dio? landing? on the beach? getting off the beach?
