the time, in November 1914, Turkish troops destroyed Christian properties and murdered several Christians at Trabzon. After November 1914 Ottoman policy towards the Greek population shifted; state policy was restricted to the forceful migration to the Anatolian hinterland of Greeks living in coastal areas, particularly the Black Sea region, close to the Turkish-Russian front. This change of policy was due to a German demand for the persecution of Ottoman Greeks to stop, after Eleftherios Venizelos had made this a condition of Greece's neutrality when speaking to the German ambassador in Athens. Venizelos also threatened to undertake a similar campaign against Muslims that were living in Greece if Ottoman policy did not change. While the Ottoman government tried to implement this change in policy, it was unsuccessful and attacks, even murders, continued to occur unpunished by local officials in the provinces, despite repeated instructions in cables sent from the central administration. Arbitrary violence and extortion of money intensified later, providing ammunition for the Venizelists arguing that Greece should join the Entente. In July 1915 the Greek chargé d'affaires claimed that the deportations "can not be any other issue than an annihilation war against the Greek nation in Turkey and as measures hereof they have been implementing forced conversions to Islam, in obvious aim to, that if after the end of the war there again would be a question of European intervention for the protection of the Christians, there will be as few of them left as possible." According to George W. Rendel of the British Foreign Office, by 1918 "over 500,000 Greeks were deported of whom comparatively few survived". In his memoirs, the United States ambassador to the Ottoman Empire between 1913 and 1916 wrote "Everywhere the Greeks were gathered in groups and, under the so-called protection of Turkish gendarmes, they were transported, the larger part on foot, into the interior. Just how many were scattered in this fashion is not definitely known, the estimates varying anywhere from 200,000 up to 1,000,000." Despite the shift of policy, the practice of evacuating Greek settlements and relocating the inhabitants was continued, albeit on a limited scale. Relocation was targeted at specific regions that were considered militarily vulnerable, not the whole of the Greek population. As a 1919 Patriarchate account records, the evacuation of many villages was accompanied with looting and murders, while many died as a result of not having been given the
