Willie returns to Flanders in spring. He is becoming traumatised by his experiences, and is beginning to endure panic attacks focused on the safety of his sisters. Jesse Kirwan’s misery and the death of the young rebel weigh on him. Meanwhile, the other Irish recruits are largely disinterested in events at home: Christy Moran, however, is indignant about the nationalists’ actions.
The men march up the line to Hulloch, where Willie writes an affectionate letter to his father affirming the patriotism of the Irishmen in the line. At stand-to a communication is relayed from HQ that a gas attack is expected. Father Buckley gives mass to the gathered battalion as the shelling before battle begins; a sign of the mortal threat anticipated ahead.
The men have taken their place in the line when gas sirens sound. Captain Sheridan makes a speech, calling on the men’s courage. A new recruit, Quigley, collapses in fear, and struggles to get his gas mask on. Willie is left to his own terror as he waits for the attack to begin. When gas finally begins to pour over the parapet, Quigley is the first to collapse; Willie is surprised by pity for the soldier. Sheridan moves the incapacitated to the rear of the trench. Willie shits himself in fear, and finds himself praying for the protection first of Jesus, then his father, then his grandfather. As the gas pours in, men struggle in their masks; Willie smells the gas, which seems more deadly than before, at St Julien.
Hand-to-hand fighting ensues as attacking Germans leap into the trench. Willie is seized upon by a German but he inadvertently skewers the man with his tomahawk, then manages to slash at the man’s head. In tearing his own mask off, the German succumbs to the gas. A melee ensues as more attackers leap into the trench, and Willie is knocked cold.
