The Explosion Most Texans Have Never Heard Of
The men on the dock thought they could put it out. A fire had broken out in the cargo hold of a French ship sitting in port, and crews were working to smother it while curious onlookers gathered along the water to watch. Local firefighters had arrived. Everything seemed like it was being handled.
Then the ship detonated.
The SS Grandcamp was loaded with over 2,300 tons of ammonium nitrate, the kind made for wartime explosives and repurposed as fertilizer after the war. When it went off that April morning in Texas City, the explosion was heard 150 miles away. A 15-foot tidal wave rolled across the harbor. Burning debris rained across the city and ignited a nearby Monsanto chemical plant. It set fire to a second ship also loaded with ammonium nitrate. That one exploded the following morning. The fires burned for two days.
581 people were killed. Over 5,000 were injured. Every ship in the harbor was sunk or destroyed. The entire fire department of Texas City, every man who had responded, was gone. It was the deadliest industrial accident in the history of the United States, and it sparked the first class action lawsuit ever filed against the U.S. government.
Most people drive right past Texas City on I-45 without knowing any of it.
