An A.D.S. of the 60th Field Ambulance under the commanding officer, Major R. V. C. Ash, had remained near Réthonvillers on the 25th until the enemy came within 500 yards. Having withdrawn from this position, Major Ash moved the whole field ambulance south to a village about a mile north-east of Roiglise. As the enemy was reported that evening to be advancing on both flanks, it was decided, after consultation with Divisional Headquarters, to retire through Roye to a point about two miles south-west of it on the Montdidier road. By the time this position was reached, about 3.20 A.M. on the 26th, information was received from the French that the enemy was on the point of entering Roye and that French troops were about to form a defensive line through the village in which the 60th Field Ambulance was established. No further information could be obtained. Major Ash continued to withdraw along the road towards Montdidier, stopping on the way to help the 53rd C.C.S. to evacuate its wounded, and collecting a large number of cases along the road. At Faverolles communication with the Division was obtained and the field ambulance marched north to rejoin, eventually arriving at Domart on the 28th. It was then decided that the Divisional transport and two out of the three field ambulances should be sent back out of the way to Abbeville. The 60th and 62nd Field Ambulances accordingly moved back that day. From this time until the 1st of April the only remaining field ambulance--the 61st--did great work. Except for a small detachment from the cavalry field ambulances there seemed to be no other medical units near. Wounded and sick from the whole Corps, from Army troops and cavalry, and from the French had to be dealt with. Every man was fed and dressed, had his case diagnosed, and was properly ticketed before being sent back. The 92nd Field Artillery Brigade was last mentioned moving back to Roiglise on the 25th, under the orders of the 30th Division. A further retirement to Beauvraignes became necessary on the morning of the 26th; and that afternoon, covered by a section of D/148 Battery and one of of the brigade withdrew to positions between Laboissière and Guerbigny and opened fire on Andechy. At 10 A.M. on the morning of the 27th the brigade came under heavy shell-fire from the direction of Erches. Shortly afterwards the French were forced out of Laboissière and the brigade was compelled to fall back to positions south-west of Favorelles, covered by the fire of B/92. At this time orders were received for the brigade to rejoin the 20th Divisional Artillery, but as the French were being hard pressed it was decided to stop and fight with the French until all ammunition was expended.
