May or may not be what you are looking for but there was a strategy boardgame that was produced in 1910 for the Boy Scouts called
Flag Raiding that was based on the capture the flag game. It wasnt a wargame though. It is shown here:

There is mention of a quasi-wargame called Scout's Chess that is played just like a wargame in that it uses an outdoor map, chess pieces to represent scouts or patrols, and is turn based. It was mentioned in the book
Scouting Games published in 1910. But there wasnt any actual board, map, or game pieces...just rules.
You would think that if a wargame had ever been made for the Boy Scouts that it would be based on events during the Boer War since Baden-Powell was in that particular war.
