Thomas Francis Enright was the first Pennsylvanian serviceman and perhaps the first American serviceman to die in World War I, along with Corporal James Bethel Gresham of Evansville, Indiana and Private Merle Hay of Glidden, Iowa. 
Early life and military service
Thomas Francis Enright was born May 8, 1887 in Bloomfield, Pennsylvania. He was the seventh child of Irish immigrants, Ellen and John Enright. He was also their first child not to be born in Ireland. He enlisted in the U.S. Army in 1909. He had served in post Boxer Rebellion China and earned the title expert cavalryman while fighting Moros during the Philippine Insurrection. By 1914, he was serving in Vera Cruz the 16th Infantry Regiment. In 1916, he was in Mexico again serving under General John J. Pershing, during his expedition to locate and capture Pancho Villa. Sometime, after this he left the army and returned to the Pittsburgh area. 
World War I service
After a short return to Pittsburgh, Enright reenlisted and joined the 16th Infantry at Fort Bliss, Texas. On 26 June 1917, the regiment disembarked in St. Nazaire, France, as part of the 1st Infantry Division. Four months later, Enright's company was moved to the trenches near Artois, France. In the early morning of 3 November 1917, the Imperial German Army attacked. After an hour of fighting, Enright, along with Corporal James Bethel Gresham, and Private Merle Hay were the first three casualties of the American Expeditionary Force.
Two days later, on 5 Nov 1917, Enright, Gresham, and Hay were buried near the battlefield where they had died. An inscription marked their graves: "Here lie the first soldiers of the illustrious Republic of the United States who fell on French soil for justice and liberty." Their bodies were eventually returned to their families and reburied in the United States. On 16 July, 1921, the city of Pittsburgh honored him with his casket lying in state at the Soldiers and Sailors National Military Museum and Memorial located in the city's Oakland section. The funeral procession was led by a gun casson drawn by six horse followed by a memorial service, led by Bishop of Pittsburgh, Hugh Charles Boyle, was held at the St. Paul Cathedral. Afterwards the procession continued to St. Mary Cemetery in the city's Lawrenceville neighborhood where Enright was reburied with full military honors after which a wreath from General Pershing was laid upon his grave.
