Appropriate enough timing. Yesterday was the anniversary of White Friday. In the first World War, and on the 13th of December in the Alpine theater there were massive avalanches, killing up to 10,000 men. Small enough in the scope of the war, but still.
Your mention of White Friday is woefully inadequate. I think it is hyperbole to say 10,000 died. As wiki notes 10,000 may have died in avalanches in December 1916.
These were Austro-Hungarian Kaiserschützen military.
White Friday occurred during the Italian front of World War I, when an avalanche struck Austro-Hungarian barracks on Mount Marmolada, killing 270 soldiers. Other avalanches the same day struck Italian and other Austro-Hungarian positions, killing hundreds. According to some reports, both sides deliberately fired shells into the weakened snowpacks in an attempt to bury the other side.
On Wednesday, December 13, 1916, at 5:30 a.m., over 200,000 tons (approx. 1 million cubic metres) of snow and ice plunged down the mountainside directly onto the barracks. The wooden buildings packed with soldiers, collapsed under the weight of the avalanche, crushing the occupants. Of the 321 troops present, 229 were Kaiserschützen mountain infantry and 102 were Bosnians from a support column. Only a few were pulled to safety while 270 were buried alive. Only 40 of the bodies were ever recovered from the pileup. Among those who survived was Captain Schmid along with his aide, who escaped slightly injured.
Note, that only 40 bodies were ever recovered, so apparently their are a lot of bodies still buried in the snow pack which has yet to melt.
Until now, it had never occurred to me that Italy was on our side in World War 1.
