One of the worst disasters in Texas history occurred on April 16, 1947, when the ship SS Grandcamp exploded at 9:12 A.M. at the docks in Texas City. The French-owned vessel, carrying explosive ammonium nitrate caught fire early in the morning, and while attempts were being made to extinguish the fire, the ship exploded. The entire dock area was destroyed, along with the nearby Monsanto Chemical Company, other smaller companies, grain warehouses, and numerous oil and chemical storage tanks. Smaller explosions and fires were ignited, by flying debris, along the industrial area and also throughout the city. Fragments of iron, parts of the ship's cargo, and dock equipment were hurled into businesses, houses, and public buildings. A fifteen-foot tidal wave caused by the force swept the dock area. The concussion of the explosion, felt as far away as Port Arthur, damaged or destroyed at least 1,000 residences and buildings throughout Texas City. The ship SS High Flyer, in dock for repairs and also carrying ammonium nitrate, was ignited by the first explosion; it was towed 100 feet from the docks before it exploded about sixteen hours later, at 1:10 A.M. on April 17. The first explosion had killed twenty-six Texas City firemen and destroyed all of the city's fire-fighting equipment, including four trucks, leaving the city helpless in the wake of the second explosion. Probably the exact number of people killed will never be known, although the ship's anchor monument records 576 persons known dead, 398 of whom were identified, and 178 listed as missing.
