Forgotten heroes (when I discovered and read the brief) begs some thought before putting paint on a figure.
I mentioned I had ideas for this June challenge on Carrion Crows blog post.
First up is one idea which has appeared to me in many previous painting challenges but I failed to act on.
Flora Sandes left the uk as a volunteer nurse to support the war against the German Empire directly. Her story is revealed here

Wikipedia carries an entry as well and probably the most commonly shown photo of Flora Sandes.
Her unique position is being the only female British woman to have officially served as a soldier in World War One.
I think Flora could be classed as a forgotten hero.
