WORK OF LAND BATTERIES
Some of the land batteries had equally hard tasks. In the middle of last November many batteries had to withstand continual attacks from the sea by Austrian battleships of the Monarch type, escorted by destroyers, which had been sent to the Venetian shore with the purpose of rendering the Piave untenable. One naval battery of medium-calibre guns, commanded successively by two brothers, fired ceaselessly, without resting, though subjected to the fire of enemy artillery and machine guns, not only from the front and side, but also from the Adriatic in the rear. During the last days of the retreat, while the defense line of the Lagoons of Venice was not yet consolidated, that battery was for a long time isolated from every communication, without food, reinforcements, or support, yet it did not cede one inch, it never slackened fire, and it never asked for help. It was one of the heroic deeds of the Italian defense between Cavazuccherina and the sea. In the afternoon of Nov. 16, though attacked by the Austrian battleships Budapest and Wien, not only did these same batteries protect the return of two Italian submarine chasers which had gone out to attack the Austrian naval division, but they effectively counterattacked the battleships and their twelve destroyers until their return in the direction of Istria. The battleships never attempted this attack again.
NAVAL AVIATION
The plain extending from Zenson to the sea does not offer any elevated points for observation and the control of artillery fire. Therefore, the task of directing the shellfire had to be confided to the airplanes, and in the lagoons to the seaplanes. But in order that the seaplanes may fulfill their work of observation with safety they must be defended from enemy airplanes and must, therefore, be escorted by chasing machines.
The Italian seaplanes and their escorts did not spare themselves. The aviators of one squadron accomplished seventy-nine bombarding and observation flights in the first twenty days of November during a total of ninety-two hours of flight—not counting practice flights.
THE SUBMARINE CHASERS
Every one now knows, at least by reputation, the M. A. S., [Motoscafi Antisommergibili di Scorta,] the Italian little armored boats that are doing effective work in the Tyrrhenean and the Adriatic, but few understand the great assistance they have given in their support of the army in the marshy Venetian plain covered with watercourses.
The M. A. S. were not built to fight on rivers, but to scour the seas; yet they are frequently seen engaging some enemy advance post. Where the enemy lines border on a river or a canal the menacing prow of an M. A. S. will now and then rise under the barbed wire of the Hungarian trenches. These swift motor boats have become the cavalry of the marshes. They are slaves to their fragility, but they have the advantage of speed and surprise.
The M. A. S. attacked the moving enemy companies across the lagoons with machine guns and their little guns. They were bombarded in turn; but their bravery and their size made them often very fortunate. At Bevazzano a big column of Honveds marching along the shore was put to flight by them. Again they shelled a cyclist corps, killing a large number. They landed a few men on ground already occupied by the enemy and succeeded in destroying or in capturing various machine-gun outposts. Elsewhere they supported isolated companies of sailors, protecting the lagoons, with their small guns. With great daring they pushed up to Porto Gruaro, which had already been invaded from Lemene. Shortly after, while the present line of Intestadure-Capo Sile-Cavazuccherina-Cortelazzo was being organized, the M. A. S. ran up and down for entire days through the Piave, the old Piave, and the Cavetta Canal, undertaking frequent sporadic fights with the machine gunners and the picked shooters of Boroevic.
The armed motor boats by themselves insured the liaison between the lines for several days, and today, when the line of resistance from the lagoons is safe, the tactical use of the M. A. S. in the interior canals is still frequent and efficacious.
