United States Catholic Chaplains in the World War - Army and Navy Chaplains Ordinariate. When the US entered WWI on April 6, 1917, the whole of the regular Army and National Guard was immediately mobilized. Realizing that the great bulk of the new big Army was made up of men who had never been away from their homes and religious environments, the government issued a hurry call for chaplains of all denominations. Catholic priests in many of the larger Dioceses were quick to respond to the call. By the time the Armistice was signed, November 11, 1918, there were 1023 chaplains in active service and 500 approved applicants. These brief biographical sketches are presented in alphabetical order. Information includes date and place of birth, school and education, theological training, ordination date, military service, rank, post-war career and residence. Additionally, there is a historical sketch of Catholic chaplains in the early wars from 1898-1917; a necrology; a list of approved applicants; and lists of chaplains in reserve corps and serving in military and naval posts, public health and veteran hospitals after the war. Illustrated with some photos of church leaders and a chart of numbers of priests active during the war. (1924), 2003, 5½x8½, paper, 360 pp.
