For Women's day - Mother Ross

Christian Davies (1667 – 7 July 1739), born Christian Cavanagh also known as Kit Cavanagh or Mother Ross was an Irishwoman who joined the British Army in 1693 disguised as a man. She fought with the infantry in Flanders during the Nine Years War until 1697, then with the 4th Dragoons, later the 2nd Royal North British Dragoons and finally with the Scots Greys in the War of the Spanish Succession from 1701 to 1706. The author Daniel Defoe met her in old age when she was a Chelsea Pensioner and turned her story into a book entitled The Life and Adventures of Mrs. Christian Davies.
