Letter (s??) from Douglas Haig?

[Jim Mackay]

I believe that the first cover was addressed and signed by Douglas Haig on Christmas Day 1915.

I've also had the second cover for some time, but have only noticed now that the second cover appears to have been addressed by the same hand.

There is a signature by the War Cabinet cachet that I can't quite make out. This cover has a feint LONDON roller cancellation of 22 Oct 15 or 16.

Any thoughts?
Regards
Jim

While there are some similarities in the writing, there are also several significant differences and I am not convinced that the two addresses were written by the same person
