Highest Battle of the War
A trench dug out of the ice in the Alps; Capt. Berni, who led the attack on Mt. San Matteo, is at right. He would be killed when the Austrians retook the mountain the next month; his body has never been recovered.
August 13 1918, San Matteo--The far western portion of the Italian front, near the border with Switzerland, had seen little large-scale fighting, apart from a diversionary attack at the Tonale pass in the lead-up to the Piave offensive. The terrain was too difficult and the conditions too harsh to support large armies. In one case, a detachment of 100 Italian soldiers had to be supported by 900 porters just to bring up their needed supplies every day. Nonetheless, fighting continued, at the smallest scales, in conditions unfit for long-term human habitation.
On August 13, a small group of Alpini seized Mt. San Matteo, a peak of over 12000 feet, in a surprise attack. Many of the defenders were captured, others fled down the peak, and still others were killed. As glaciers have retreated from the area in the past few decades, several bodies from the battle, mummified by the conditions, have been found in the area.
In early September, the Austrians sent a force of 150 men to retake the mountain, with a large amount (for the area) of artillery support. The Italians, knowing they could not hold onto the peak, began shelling it themselves as well, killing many of their own defenders. The operation would be the last Austrian victory in the war; they would lose the mountain in the peace treaty. The fighting on Mt. San Matteo was the highest-altitude warfare in the First World War; war in similar conditions would not be fought again until the 1960′s, when India and China battled in the Himalayas.
