I don't think that the British Army had ready troops, fit for a campaign in Finland. The results in Norway point in that direction. The ground forces were not equipped for an arctic adventure, and any TA units sendt would have the same troubles as they did in Norway.

Not sure how many planes they could send, but that would probably be the most effective help that Britain could give.

The French is another story. Their chasseurs de alpin would have done well, (as they did in the Norwegain campaign) but the foreign legion would have all been shot by the Finns. (The ruddy bastards plundered and raped in Norway)

It follows the grand strategic lines of the allies. France provide the Army, and the British the sea. Both in the air.

The Finland adventure was just a lot of hot air, and a miracle that they did not squander men up there. However, IF they'd moved up there and experienced how awful they performed, WOULD they have begun to revise some of their operational shortcomings??
