The German attack began on 24 October amid rain and snow, which never deterred the Germans, and on this occasion even assisted them by increasing the element of surprise. The infected front of the Second Army between Zaga and Auzza broke with such celerity that by dawn of the 25th Von Buelow's men had crossed the Isonzo, scaled Mount Matajur, 5000 feet high, and were pouring across the Italian frontier; and the gains of twenty-nine months were lost in as many hours. Elsewhere Italian troops fought with splendid determination, and the garrison of M. Nero held out for days and died to a man, while their comrades at Caporetto greeted the enemy with white flags, and reserves withheld their assistance. Gallantry to the left and right availed nothing against poltroonery in the centre: the Bainsizza plateau was lost, and the Third Army on the Carso was in dire peril of being cut off from its retreat. Nothing but retreat, and perhaps not even that, was open to the other armies, with the Second in the centre fleeing like a rabble and Von Buelow threatening the left and right in the rear. On the 27th Cividale, on the 28th Gorizia, and on the 29th Udine, twelve miles within the Italian frontier, fell, and Von Buelow had taken 100,000 prisoners and 700 guns. The Third Army escaped by the skin of its teeth, the excellence of its discipline, and the sacrifice of its rearguards and 500 guns at the crossing of the Tagliamento at Latisana on 1 November. Then the rain came down, and no believer in Jupiter Pluvius as a German god could maintain that that river had been turned into a roaring torrent in the interests of the German pursuit.
