The 60th, 61st and 62nd Field Ambulances had been attached respectively to the 59th, 60th and 61st Brigades, but during the successive retirements they had to deal with the casualties of many different units. Their work was splendid. Many times when communication was difficult and the situation uncertain, advanced dressing stations were established close to the front line and the wounded carried back, often under heavy fire, with great perseverance and courage. On the 22nd, between 2000 and 3000 cases passed through a temporary aid post of the 60th Field Ambulance established at Matigny by Major C. A. Boyd before the post was abandoned at the last possible moment that night when the enemy was entering the village. Major Boyd and his party crossed at Voyennes just before the bridges were destroyed. At 8 A.M. on the 23rd the enemy was reported to have broken through at Ham and to be advancing on Esmery Hallon, through which the 30th Division was retiring towards the Libermont Canal. Brig.-General Duncan was ordered to counter attack, and elements of the 182nd Brigade (61st Division) were placed at his disposal to assist this operation. Lieut.-Colonel Bilton, of the 61st Division, was placed in command of the counter attack, and was assisted by Major A. E. Sanderson, the Brigade Major of the 60th Brigade. Lieut.-Colonel Bilton moved off with about 800 men and at 4 P.M. launched the attack from the main Ham--Nesle road, about 1500 yards west of Eppeville. The attack, delivered with great dash, drove back the enemy, captured Verlaines, and restored the situation. The Division held the canal crossings throughout the day in spite of many attempts by the enemy to force them. Fighting was heavy at Offoy on the front of the 12th K.R.R.C.; at Béthencourt the 11th R.B. drove back with considerable loss several parties which tried to cross the canal. In the evening the 182nd Brigade (61st Division), which had been under the orders of Major-General Douglas Smith since the morning, was transferred to the 30th Division, and the 183rd and 184th Brigades (61st Division) came under the 20th Division for counter-attack purposes and moved to Nesle. The Division was further reinforced by two batteries of a Canadian Motor Machine Gun Battalion under Capt. Merling. “In all subsequent operations,” the official report states, “up to the 31st March, these batteries performed yeoman service, and on account of their mobility were of inestimable service in holding the extended fronts allotted to the Division.”
