In the autumn of 1914, a month and a half before the beginning of Turco-Russian hostilities, Dr. Pasdermadjian went to the Caucasus on a special mission, and joined the committee which had been appointed by the Armenian National Council of the Caucasus to organize the Armenian volunteer movement. In November of the same year, when the Russo-Turkish war had begun, he accompanied the second battalion of the Armenian volunteers, as the representative of the executive committee of Tiflis, to prepare the local inhabitants of Turkish Armenia for self-defence, as the Russian army was about to advance into the captured territories of that country. On November 14 the second battalion of the Armenian volunteers engaged in battle for the first time, near Bayazid, with the Turkish soldiers and the Kurds. In the course of a bloody combat which lasted twenty-four hours, Dro, the brave commander of the battalion, was seriously wounded, and Dr. Pasdermadjian 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. In the summer of 1915, Dr. Pasdermadjian (again as a representative of the executive committee of Tiflis) went to Van. He was there when the people migrated en masse to the Caucasus (when the Russian army was forced to retreat to the old Russo-Turkish frontiers) and shared their untold hardships. In the spring of 1917, when the Russian Revolution turned all the defence work of the Caucasus up-side down, Dr. Pasdermadjian, with Dr. Zavrieff, was sent from the Caucasus to Petrograd to negotiate with the temporary Russian government concerning Caucasian affairs. From Petrograd he left for America in June of the same year as the representative of the Armenian National Council of Tiflis and as the special Envoy of His Holiness the Catholicos of all the Armenians, to lay before the American public and government the sorrows of the Armenian people with the view of winning their sympathy and protection for the indisputable rights of Armenia. He is still acting in that capacity with all the energy at his command. His last effort has been the preparation of this pamphlet, in which the reader will find a part of these biographical facts under his assumed name of Armen Garo. A word or two more about this booklet, which has been written in the nick of time.
