Isaac was with the Royal Engineers when the call out for skilled laborers to fill out infantry pioneer battalions was made. He was transferred to the 6th Battalion, East Yorkshire Regiment in 1917. Pioneer battalions were employed as a form of combat engineers; building up trenches, defensive position and general jobs repairing damage left by artillery. It was hazardous duty and a thankless job.
