After five days, during which he used almost all his money, Riis found work as a carpenter at Brady's Bend Iron Works on the Allegheny River above Pittsburgh. After a few days of that, he began mining for increased pay but quickly resumed carpentry. Learning on July 19, 1870, that France had declared war on Germany, he expected that Denmark would join France to avenge the Prussian seizure of Schleswig, and determined to fight for France. He returned to New York, and, having pawned most of his possessions and without money, attempted to enlist at the French consulate, but was told that there was no plan to send a volunteer army from America. Pawning his revolver, he walked out of New York until he collapsed from exhaustion; on waking, he walked to Fordham College where a Catholic priest served him breakfast.
