Lord Dundonald's camel ambulance packed for transport, late 19th century

"In areas inhospitable to wheeled transport, the British relied upon the traditional camel litter, or kijjawa, and even experimented with a modified camel ambulance, invented by Lord Dundonald of the British Army. The ambulance accomodated two recumbent or eight seated patients and proved so compact that, when disassembled, it could be carried on the back of a camel." – according to Battlefield Medicine: A History of the Military Ambulance from the Napoleonic Wars Through World War I, by John S. Haller
