Bryce 's accounts were confirmed by Vernon Lyman Kellogg , director of the American Commission for Relief in Belgium , who told the '' New York Times '' that the German military enslaved hundreds of thousands of Belgian workers and abused and maimed many of them in the process . Bryce also strongly condemned the Armenian Genocide in the Ottoman Empire , mainly in the year 1915 . Bryce was the first to speak on that subject in the House of Lords , in July 1915 . Later , with the assistance of the historian Arnold J. Toynbee , he produced a documentary record of the massacres , published by the British government in 1916 as the '' Blue Book '' . In 1921 , Bryce wrote that the Armenian genocide had also claimed half of the population of Assyrians in the Ottoman Empire and that similar cruelties were perpetrated upon them
