British Army Royal Horse Artillery Bombardier Billy Elder is a team master for the horses and mules that pull the 13-pounder guns on the Western front. It’s hard work, but before long Billy befriends a tenacious mule named Broonie who goes above and beyond the call of duty in the Battle of Somme, saving countless lives through persistence alone. Despite gas attacks, shelling and aerial artillery, it seems Broonie is too stubborn to die and inspires those around him to be the same!
