Jens Larssen bicycled through Pontiac on his way to the Metallurgical Laboratory after the early stages of the Battle of Chicago. He had previously heard of the town in connection to its prison, which he saw in ruins with a wrecked American fighter plane lying nearby. The rest of the town was in no better shape, with machine gun bullets dotting the courthouse, and a monument to the city's namesake broken in pieces.
