orgola Pass toward the south
and lost three more twenty-eight centimeter howitzers and 3,000 men,
84 officers, 25 guns and 8 machine guns.

Austrian aeroplanes dropped bombs on Vicenza.

Although the Italian line still held in the main, it could not deny
Austrian advances at certain important points. Slowly the
Austro-Hungarians pushed on everywhere toward the Italian frontier. On
May 21, 1916, an attack of the Graz Corps on Lavarone Plateau was
attended with complete success. The Italians were driven from their
entire position. Other Austrian troops captured Fima, Mandriolo and
the height immediately west of the frontier from the summit as far as
the Astico Valley.

The troops of Archduke Charles Francis Joseph reached the Monte
Tormino Majo line.

Between the Astico and Brenta, in the Sugana Valley, the Austrian
attacks likewise continued, supported by powerful artillery, against
advanced lines in the west valleys of Terra Astico, Doss Maggio and
Campelle.

Since the beginning of the offensive 23,883 Italians, among whom are
482 officers, had now been captured and the number of cannon taken had
been increased to 172.

Between Lake Garda and the Adige large Austrian forces were massed on
May 22, 1916, in the Riva zone. There was also considerable aerial
activity on that day on Monte Baldo (the mountain ridge to the east of
the lake). From the Adige to the Astico there were only
reconnoiterings. Between the Astico and the Brenta Rivers in the
Sugana Valley, the Italians were again forced to fall back gradually
on their main lines after repulsing heavy attacks throughout the day.
The retreat, however, was orderly and spontaneous.

Besides accomplishing their advance in the Val Sugana, the Austrians
continued the reduction of the forts protecting Arsiero, well across
the Italian frontier on the way toward Vicenza. Arsiero is the
terminus of a railway leading down into the Vicenza plain and the city
of Vicenza. Through the capture of the Spitz Tonezza and Monte
Melignone the Austrians now held the entire line across the frontier
as far as Forni on the Astico. They also pushed their advance toward
the ridge north of the Val dei Laghi, and toward Monte Tormino and
Monte Cremone, all three outlying defenses of Arsiero. Meanwhile the
right wing of the Austrian army, after storming Col Santo, had moved
toward Monte Pasubio, and the left wing had stormed the Sasso Alto,
commanding the Armentara Ridge, enabling the Aust
