On 14 November, at the Bergmann Offensive, the second battalion of the Armenian volunteers engaged in battle for the first time, near Bayazid. In the course of a bloody combat which lasted twenty-four hours, Dro, the commander of the battalion, was seriously wounded, and Armen Garo was forced immediately to take his place. From that day to March of the following year, he remained at the head of that battalion, and led it into eleven battles in the neighborhood of Alashkert, Toutakh, and Malashkert, until Dro recovered and returned to resume the command.
