[Bigkahuna]

Not only when our heroes arrive at Fort William Henry as mentioned by Bigkahuna, but in the extended version there is a scene where the Major Hayward commands a detachment of Highlanders to create a diversion for the runners leaving the fort.

Of course, there were no Highland troops at Ft William Henry, but why spoil the beauty of the thing with reality.

There were some Highland troops serving with Rogers Rangers, on detached duty so to speak, in order to learn the Ranger style of warfare.
