Fourth Battle of the Isonzo

The Italian Third Army, covering the rest of the front up to the sea, launched a series of large attacks which brought no significant gain.

The intensity of the fighting increased until the end of November, when the bridgehead of Tolmin (Tolmino) was heavily shelled and casualties peaked.

In the first fifteen days of December, however, the fighting was reduced to small scale skirmishes as opposed to the massive frontal assaults that characterized the previous phases of the battle.

An unsigned truce on the Karst Plateau was made as the temperatures dropped, and operations were ceased due to lack of supplies.

The Austro-Hungarian High Command, worried by huge losses, requested assistance from the German Empire, which was not yet formally in the war against Italy.
