The book traces Brigadier General William Glasgow's 13th Infantry Brigade from formation in Egypt in 1916 to its costly double encounter with the enemy at Mouquet Farm. It then follows the brigade into 1917 with difficult victories at Noreuil and Messines and an easier advance at Zonnebeke. The book concludes with the brigade's halting of the largest-ever German attack on Australian troops at Dernancourt on 5 April 1918 and, three weeks later, its triumph at Villers-Bretonneux.
