The exact origin of this hurricane is unknown, but it likely formed off the coast of Cuba before heading on a west-northwest track towards the Gulf Coast. A small hurricane, it reached an estimated Category 3-4 strength before making landfall on July 27 in southeastern Louisiana, bringing heavy winds and a 5–6 ft storm surge. The hurricane continued northeastward, making a second landfall in Bay St. Louis, Mississippi before dissipating inland. Known as one of the most destructive hurricanes to affect the United States during the first half of the 19th century, the Bay St. Louis Hurricane caused severe damage across Alabama, Louisiana, and Mississippi, leaving behind the remains of shattered buildings and uprooted trees. Several vessels (from small boats to 60-ton brigs) were driven ashore by the hurricane's storm surge. One of them was the capsizing of the U.S. warship Firebrand, drowning 39 sailors. Several U.S. solders were caught off guard by the hurricane and died in its midst. There were also reports of people being attacked by alligators, snapping turtles, and snakes, which further added to the death toll. The hurricane caused over $100,000 dollars (1819 US dollars) in damage, and killed between 43 and 175 people, some of them later found washed up across the Gulf Coast.
