On the night of 10/11 June 1944 two platoons of B Company with supporting arm made a reconnaissance in force through a strongly held German defensive position, at the bridge at Putot-en-Bessin. Corporal (Acting Sergeant) Frost was acting as Platoon Sergeant of the left flanking Platoon. Before reaching the line of the railway, his Platoon commander was made a casualty. Frost immediately took hold of the Platoon and showed outstanding leadership. He personally accounted for three of the enemy, and by coolly sighting his nearest Bren gun enabled his Platoon to continue forward when pinned down by vicious cross-fire and Mortar “stands”.
On returning to the Company area under heavy fire from heavy mortars and machine-guns, Frost came across remnants of the other platoon. One of these men, Private Ives, was severely wounded and could not make his way back. Frost carried him through the heavy fire to the safety of his own lines and the R.A.P., thereby saving his life.
Throughout this action Frost remained an outstanding example to his men, and in saving the life of Ives showed devotion beyond the call of duty.
