This shows a heavy artillery gun being transported along a road towards the Front at Ypres. The gun, strapped to an eight-wheeled carriage, is being hauled by a tractor with massive tracked back wheels. Heavy artillery guns were difficult and slow to move, so they needed to be manoeuvred into position well before a new offensive.
