We reveal an ambitious archaeological project in Southern Jordan, which is providing startling new evidence. The Great Arab Revolt Project (GARP) is one of the only archaeological investigations of a battlefield on this scale anywhere in the world. While the archaeological trace of Lawrence and the Bedouin guerrilla fighters is by its very nature incredibly scarce, the military structures of their opponents, the Ottoman Turks, are all too evident. The structures and scars from this battle are visible across the desert, in particular around the city of Ma an, a key Hejaz station. On-the-ground analysis of surviving defences begins to reveal the style of warfare played out in this military arena.
