Modern motor ambulances and primitive mule stretchers used to transport wounded soldiers.
World War One: transporting the wounded at the Salonika front in Greece (aka Thesalonika) during the Allies push northward.
Various shots of primitive methods of moving wounded: mules dragging stretchers with wounded men lying on them, two mules with two poles tied between them forming a frame for a stretcher and a two-wheeled cart pulled by a mule, able-bodied men walk alongside long line of mules.
Various shots of modern equipment: fleet of Red Cross motor ambulances driving away. Ambulances drive in line over dirt, stirring up dust. Tents of army camp in background.
