On 2 January 1919, Gough-Calthorpe requested from the Foreign Office authority to obtain the arrest and handing over of all those responsible for the incessant breaches of the terms of the Armistice and the continued ill-treatment of Armenians. Calthorpe got together a staff of dedicated assistants, including a notable anti-Turkish Irishman, Andrew Ryan, later Sir, who in 1951 published his memoirs. In his new role as the chief Dragoman of the British High Commission and Second Political Officer, he found himself in charge of the "Armenian question". He proved instrumental in the arrest of a large number of the (later to be) Malta deportees. These fell broadly into three categories: Those still breaching the terms of the armistice, those who had allegedly ill-treated Allied prisoners-of-war and those responsible for excesses against Armenians, in Turkey itself and the Caucasus. Calthorpe asked for a personal interview with Reshid Pasha, Ottoman Minister of Foreign Affairs, to impress on him how Britain viewed the Armenian affair and the ill-treatment of POWs as "most important" deserving "the utmost attention". Two days later Calthorpe formally requested the arrest of seven leaders of the Committee of Union and Progress (CUP). While between 160 and 200 people were arrested, another 60 suspected of participating in the massacre of Armenians remained at large.
