Good old HG Wells...he was very funny.
"LITTLE WARS is the game of kings - for players in an inferior social position. It can be played by boys of every age from twelve to one hundred and fifty - and even later if the limbs remain sufficiently supple - by girls of the better sort, and by a few rare and gifted women."
"A Game for Boys from twelve years of age to one hundred and fifty and
for that more intelligent sort of girl who likes boys' games and books"
"Primitive attempts to realise the dream were interrupted by a great
rustle and chattering of lady visitors. They regarded the objects upon
the floor with the empty disdain of their sex for all imaginative
things"
The answer is at the top of Scott's post.
These are from the book "Little Wars" by HG Wells published in 1913.
