The Lost Battalion is the name given to nine companies of the United States 77:th Division during the battle of the Argonne in 1918.
Even though these 550-575 brave men were completely surrounded by the German army and subjected to friendly artillery fire they kept on fighting for a week until they were relieved.
Of the over 500 soldiers who entered the Argonne Forest, only 194 walked out unscathed.
The rest were killed, missing, captured, or wounded.
