Honoring America’s Unknown Soldiers
After World War I, Congress wished to honor the more than 116,000 American soldiers who lost their lives in the war. Most were buried overseas, and hundreds remained unidentified or missing. Letters from the public begging for the return of loved ones’ remains and widespread news coverage of the French and British Unknown Soldier burials established after the war prompted Congress to pass a resolution in 1921 to develop an Unknown Soldier memorial in the United States.
I . . . had first-hand knowledge of the brave sacrifices made by American forces during the First World War, and I wanted America, as a beacon of freedom and democracy, to have her own memorial to honor the Unknown Soldier.
