In The Green Wall, the story unfolds on July 4, 1944, amidst the chaos of the D-Day invasion in Normandy. Sergeant Curtis Culin, a member of the 102nd Recon, narrates the harrowing experiences of his tank unit as they navigate the battlefield. The celebratory fireworks of Independence Day are overshadowed by the sounds of war, as Culin and his comrades face the enemy and the treacherous hedgerows that define the landscape. These thick, green walls of foliage and dirt not only obstruct their path but also conceal hidden dangers, leading to the tragic death of Culin's friend, Sergeant Joe Dobson, who is caught in a deadly ambush while attempting to breach the hedgerow.
