The Trincea delle Frasche, an Austrian fortress trench built of concrete with pre-fabricated cover elements, was situated on the Karst behind Sagrado and on the road between Castelnuovo and S. Martino. Our infantry corps repeatedly attacked this trench together with the Trincea dei Razzi right next to it, during the III and IV Battles of the Isonzo. On the 23rd October 1915, after having fought a long and hard battle, the Siena Brigade 32nd Infantry Regiment, among whose enlisted men were the volunteers from Milan, managed to set foot in the trench for the first time. In the ferocity of the assault Filippo Corridoni fell. In the trench they had gained, the infantrymen withstood the violence of the enemy assaults for the entire following night, but under a savage bombing and not getting any backup, they were compelled to abandon it. A local ceasefire was then agreed in order to evacuate the wounded and the dead of both sides, but the body of Corridoni was never found.

"On the morning of the 24th after the Austrians had regained the trench the battlefield was such a dreadful sight that the two opponents decided to sign a temporary two-hour ceasefire to evacuate the wounded and dead. This was an exceptional event. As the artillery remained quiet because of the ceasefire agreement, even their men left the trench to evacuate the wounded, but Corridoni was never found".

On the 28th day of the same month the 1st Bersaglieri Regiment bis (then the 15th), managed to impetuously gain the trench and shift the front line. Later that day, being violently attacked on all sides the regiment was compelled to fall back though it maintained Hill 164. The final honour of the victory was ascribed to the Sassari Brigade (151st and 152nd infantry, for the Austrians the Rote Teufel, red devils, from the colour of their shoulder tags). On the 12th November, the brave infantrymen of the Sassari, moved right under rival lines and occupied two dolina (a loan from the Slovenian language meaning valley), right in front of the lines and thanks to the sacrifice of the brave patrols, they managed to cut through the barbed wire entanglements.

"Other platoons of the 151st and 152nd moved forward with extraordinary devotion lead by the example of the officers. Under heavy artillery and machine gun fire and after several repeated assaults they managed to seize the Trincea delle Frasche trench position."

The Austrians were forced to surrender and the following day also the Trincea dei Razzi was gained. Close to the Frasche trench, there are today the memorial stone to Corridoni and that to the Sassari Brigade. Further on along the "Tortuosa" track there is the Dolina dei Bersaglieri connected to the Frasche trench by means of a gallery. The gallery that was skillfully dugout and exploited by the Austrian soldiers, was then re-adapted and expanded by the Italian troops once they had gained it.
