J. H. Morgan, Leaves from a Field Note-Book
“ Field ambulances, like the batteries, are somewhat migratory in their habits, and change their positions [Pg 98] according as they are wanted. But a field ambulance is not, as might be supposed, a vehicle but a unit of the R.A.M.C, with a major or a colonel in charge as O.C. The A.D.M.S. of a division has three field ambulances under him, and when an attack in force is projected he mobilises these three units at forward dressing stations in the rear of the trenches. They are a link between the aid-posts in front and the collecting stations behind. ”
