We have three prize bundles up for grab, with three winners in total, each bagging one copy of Walking Gallipoli, one copy of Infantry Small Arms of the 21st Century and one copy of Britain in the Age of Arthur.
The prizes have been supplied thanks to the generosity of specialist military book publisher, Pen and Sword.
The three competition winners will be drawn at random from those with the correct answer. All you have to do is answer the question correctly.
