In all the other sectors very much the same conditions prevailed. Artillery fire was maintained on both sides almost constantly. Infantry attacks were launched wherever and whenever the slightest opportunity offered itself. Scarcely any of these, however, resulted in any noticeable advantage to either side, especially in view of the fact that whenever one side would register a slight gain, the other side immediately would respond by counterattack and frequently nullify all previous successes. Comparatively unimportant and restricted, though, as most of this fighting was, it was so only because it exerted practically no influence on the general situation. On the other hand, it was carried on with the greatest display of valor and persistence that can be imagined and, because of the very nature of the ground on which it occurred, it forms one of the most spectacular periods of the war on the Austro-Italian front. Of these many local operations there were only a few which developed to such an extent that they need to be mentioned specifically. One of these was a series of engagements in the Ledro Valley, southwest of Riva and west of Lake Garda. There the Italians on April 11, 1916, by systematic offensive actions, pushed their occupation of the heights north of Rio Tonale, between Concei Valley and Lake Garda. Efficaciously supported by their artillery, their infantry carried with the bayonet a strong line of intrenchments and redoubts along the southern slopes of Monte Pari Cimadoro and the crags of Monte Sperone. On the following day, however, April 12, 1916, the Austro-Hungarians, by violent surprise attacks, succeeded in rushing a part of the trenches taken by the Italians at Monte Sperone. In the evening, after an intense preparation by artillery, Italian infantry counterattacked, reoccupying the lost positions, after a deadly hand-to-hand struggle and extending their occupation to the slopes of Monte Sperone. This was followed by a still further extension on April 16, 1916. Much of the fighting involved positions on mountain peaks of great height, creating difficulties for both the attacker and the defender, which at first glance appeared to be almost insurmountable. Of this type of warfare in the high mountains, the special correspondent of the London "Times" gives the following vivid description: "The Italian dispositions are very complete, and it is at this point necessary to say a few words upon Alpini warfare, which the Italians have brought to such a pitch of perfection. They are not the only mountaineers in the world, nor the only people to possess warriors famous on the hillside, but they were the first people in Europe, except the Swiss, to organize mountain warfare scientifically, and in their Alpine groups they possess a force unrivaled for combat in the higher mountains. The Alpini are individualists who think and act for themselves and so can fight for themselves. They are the cream of the army.
