He is saying the back drop for the game is the 7 Years War... so long all previous games... killing guards and soldiers from the nations involved in the war will happen.

When have the Templars ever sided with the British? Just this one time.

The game, I am sure, will explain the reason for the Templars aiding the British during the 7 Years War.

But, simply, we can French ships/troop/guards because they were there in the time period.
