He served as Captain Jack Zimmerman's right hand man during the landing operations on D-Day, and was among the soldiers who found the naked Nigel Griffin in a barn near Carentan. They were informed about the weather machine that was believed to pose a threat to the Allied fleet. Captain Zimmerman decided to help Griffin get into the bunker where Helen Magnus and James Watson were being interrogated. The sergeant then fought alongside his fellow soldiers outside the bunker; he was left astray, but regrouped with backup forces who helped him find Captain Zimmerman.
