The PS General Slocum was a sidewheel steam passenger ship, also known as a paddle steamer, built at Brooklyn, New York in 1891. The General Slocum was named for Civil War officer and New York Congressman Henry Warner Slocum. She operated in the New York City area as an excursion ship for the next thirteen years under the same ownership. During her service history she was involved in a number of mishaps, including multiple groundings and collisions. On June 15, 1904, the General Slocum caught fire and burned to the waterline in New York's East River. At the time of the accident she was on a chartered run carrying members of St. Mark's Evangelical Lutheran Church (German Americans from Little Germany, Manhattan) to a church picnic. An estimated 1,021 of the 1,342 people on board were killed.
