truck containing Irish Free State soldiers and a mattress, driven by a man in civilian dress

Photograph of a truck containing Irish Free State soldiers and a mattress, driven by a man in civilian dress, which may have just completed the crossing of the bridge; a group of small boys is seated and standing on the wall of a river; many are waving their hats in jubilation; one little boy is barefoot, another is wearing a school uniform and is holding his school bag; other soldiers and an army vehicle are visible in the distance on the bridge.
