For conspicuous bravery, leadership and devotion to duty on 27 Sept. 1918, across the Canal Du Nord, near Graincourt, when in command of a company detailed to capture the canal crossing on the Demicourt-Graincourt road. On reaching the canal, the leading platoon came under annihilating machine-gun fire from a machine-gun post under the old iron bridge on the far side of the canal, and was unable to advance, despite reinforcing waves. Capt. Frisby realised at once that unless this post was captured the whole advance in this area would fail. Calling for volunteers to follow him, he dashed forward, and with three other ranks, he climbed down into the canal under an intense point-blank machine gun fire, and succeeded in capturing the post with two machine-guns and twelve men. By his personal valour and initiative he restored the situation and enabled the attacking companies to continue the advance. Having reached and consolidated his objective, he gave timely support to the company on his right, which had lost all its officers and sergeants, organised its defences, and beat off a heavy hostile counter-attack. He was wounded in the leg by a bayonet in the attack on the machine-gun post, but remained at duty throughout, thereby setting an excellent example to all ranks.
