Battles of the Isonzo
As a nationalist, Gabriele D'Annunzio was angered by what he considered to be the surrender of an Italian city. On 12 September 1919, he led a force that was about 2,600-strong and drawn mostly from former or serving members of the Granatieri di Sardegna brigade of the Royal Italian Army, as well as Italian nationalists and irredentists. Many members of D'Annunzio's force were reputedly veterans of the Battles of the Isonzo.
