Warfare in the high Alps, with their difficult communications, is necessarily carried on by comparatively small bodies of men. The vast masses of the Western and Eastern fronts could not possibly be maintained among the crags and glaciers of the Italian frontier. Operations by single battalions have all the importance of a divisional attack elsewhere. In this case one battalion had been allotted the task of storming and retaining the enemy's position. In the little low timber hut sunk beneath the snow-level which was the battalion headquarters, the captain found the colonel commanding the regiment in conference with the local commander and the company leaders. The atmosphere of the cramped interior was thick with the exhalations of the half-dozen men, warm with the heat of a petrol-stove. Capitano Ricci saluted the colonel, was received affably. A pair of keen eyes under level brows appraised him, smiled upon him. For his benefit the colonel recapitulated. "The plan is briefly this. The artillery is cutting the wire and shelling the trenches immediately in front of us. The Austrians of course will assume that we are going to attack there. They will keep strong reserves at hand in the vicinity--as strong as they can, for we know that there is no very large force opposite. The artillery is making it difficult to bring up the reserves from the rear. All their communications are under fire. Now, we hope that the enemy will concentrate on the damaged trench in front of us. The attack is being made by four companies. One company will advance at 9 p.m., using every precaution not to be seen, and will cross the glacier at an angle to its right. It will fall upon the enemy's trench here"--he indicated a spot on the left of the enemy's position as marked on a plan spread over the table. "It should effect a surprise as the enemy will be far from expecting an attack on a part of the line which has not been bombarded at all. Directly that attack gets into the trench it will turn to the left and continue to press on as hard as possible. If it is progressing well it will send up a green rocket. If it is in difficulties it will send up a red rocket. The second company will advance to within about a hundred metres of the trench that has been bombarded. There it will halt. If matters go as I expect them to, the company on the right will send up a green rocket. Then the Austrians, realising that they have made a mistake, will rush up their men from the damaged sector and put up a resistance. The green light will be followed by a red one which will automatically indicate that the enemy's reserves are engaged. _Whenever that red light goes up_, whether preceded by a green one or not, the second company will rush the trench in front of it. I hope that it will find it thinly held. The third company will advance, with every precaution, at 9.30 p.m. in support of the second company. The fourth company I will retain as general reserve under my command.
