I have read quite extensively of this period due to having a lot if Dutch friends and have not read or seen anything about the US army on Northern Holland and it was the Canadians forces who liberated Amsterdam. Is that who your grandfather meant?

No they were not, they were used exclusively in the east following the invasion of Poland and operated as part of the final solution. They were never used in Holland.

The Einsatzgruppen never operated in Holland is your grandfather mistaken in what German unit's footwear was used?

where exactly was this school located? what was its name? can we at least have a few details to prove your story. even a street name and town would be a start.
