The sister of Bottecchia had brought me the sheets which we were going to use as signals and cautiously we approached the place where they were to be extended. We traversed the little field once again so as to be certain we were not making a mistake, and by half-past twelve the sheet was in its proper place. We hid behind a tree on the other side of the river to guard it and hinder any petty thief from stealing the precious material. The sky which at first was very clear was streaked with those small light clouds which indicate that in the higher strata of the air a swift wind is blowing. Above the clouds a squadron of enemy planes, readily recognizable from the heavy noise of their motors, was completing a series of slow evolutions. These aeroplanes, whose task was certainly to obstruct the way for any of our planes, cruised continually between Vittorio and Pordenone. We glanced at the little watch given to Giovanni by his sister; it was 12.55. Suddenly the anti-aircraft battery near us began to fire. Yes, they had come. After a few seconds we glimpsed among the clouds a reconnoitring plane escorted by three chasing planes. And now what would happen; now that four of our aeroplanes would be against twelve of theirs? The adversary’s chance in attack was better than ours because they were able to rise above the clouds and crash down unexpectedly on our planes which, flying beneath them, were certainly not aware of their presence. I distinctly heard the cadenced, sibilant note of our motors and the deeper, heavier noise of the enemy motors. In a second the enemy had divided into two platoons of six planes each and each had selected its own objectives. Six had placed themselves against our reconnoitring plane and six were combating our three chasing planes. From among the clouds I heard the first faint reports of the machine-guns. The reconnoitring plane which appeared and disappeared among the white curls did not let itself be surprised; at times it made some daring evolutions and seemed as if it were going to nose-dive forever but retook its position and answered with brief rallies to the prolonged bursts of fire from the enemy guns. The Austrians in accord with their usual tactics tried to keep our plane in play with a concentration of their forces so that finally one of them could attempt a fatal volley, but our pilots did not lose heart and with repeated tricks and wiles endeavored to escape the net. There!—five planes had surrounded it, and one all painted red, the swiftest, a “D 5,” tried to take position on its tail. I held my breath; the enemy plane was but a few yards from our plane and fired lengthy bursts at it but ours answered only with a brief volley. Suddenly the Austrian plane reeled and seemed to go out of control; for a time it spun downward like a dead leaf, and finally nose-dived in a great flame. I raised my arms in the air; I wished to express to that little speck with the tricolor all my joy, all my satisfaction.
