Graduates entering the army were presented to King William I, who asked for their father's name and rank. He became a second lieutenant in the Third Regiment of Foot Guards. In the Prussian Army Action in two wars When the Austro-Prussian War of 1866 broke out, Hindenburg wrote his parents: "I rejoice in this bright-coloured future.
