The Battle of San Matteo took place in the late summer of 1918 on the Punta San Matteo (3,678 m) during World War I. It was regarded as the highest battle in history until it was surpassed in 1999 by the Kargil Conflict at 5,600 m. At the beginning of 1918 Austro-Hungarian troops set up a fortified position with small artillery pieces on the top of the San Matteo Peak. The base of the peak lies at 2800m altitude and it takes a four-hour ice climb up a glacier to reach the top. From this position, they were able to shell the road to the Gavia Pass and thus harass the Italian supply convoys to the front line. On August 13, 1918, a small group of Alpini mountain troops (308th Company, Battalion "Monte Ortler") conducted a surprise attack on the peak, successfully taking the fortified position.
