The1856 Last Island hurricane (also known as theGreat Storm of 1856) was a deadly and destructivetropical cyclone that is tied with 2020'sHurricane Laura and 2021'sHurricane Ida as the strongest hurricane on record to makelandfall in the U.S. state ofLouisiana, as measured bymaximum sustained winds.^[1] The first known tropical cyclone of1856 Atlantic hurricane season, it was observed first as a minimal hurricane in the Gulf of Mexico nearDry Tortugas on August 9. Moving northwestward, the cyclone quickly intensified into a strong Category 4 hurricane on the modern-daySaffir–Simpson scale by the following day. Late on August 10, the hurricane made landfall onLast Island, Louisiana, with winds at 150 mph (240 km/h), hours before striking nearNew Iberia. The system rapidly weakened after moving inland, falling to tropical storm intensity on August 11. The storm would be last noted overMississippi on the next day.

Offshore, at least 183 people drowned after steamers and schooners sank in rough seas produced by the hurricane. Astorm surge between 11 and 12 feet (3.4 and 3.7 m) completely submerged Last Island in Louisiana, destroying virtually every structure, including the hotels and casinos, while all crops were ruined. Additionally, Last Island itself was split in two. Inland, heavy rainfall caused theMermentau River to flood, destroying crops and every house inAbbeville. The storm produced as much as 13.14 inches (334 mm) of precipitation inNew Orleans. InPlaquemines Parish, rice fields were under several feet of water, while many orange trees lost their fruit. Overall, the hurricane resulted in at least 300 fatalities.

Thecyclone was first detected in the easternGulf of Mexico 125 miles (201 km)west-northwest ofKey West, Florida, on August 8, 1856. Because it was already a hurricane when it was first observed, it probably had developed further east than here. It advanced steadily northwest, strengthening to the equivalent of aCategory 3 hurricane. The hurricane gradually slowed prior to landfall on August 10, and it attained its estimated peak intensity of 150 mph (240 km/h). It was a tropical cyclone of small diameter, and itsmaximum sustained winds may have reachedCategory 5 status, but were unrecorded. During the early evening of August 10 the northeastern edge of theeye crossed over Last Island (Official name:Isle Dernière) before makinglandfall a few hours later south ofNew Iberia, Louisiana. The cyclone is believed to have struck southern Louisiana at peak intensity with an approximatecentral pressure of 934 mbar (27.6 inHg).^[2] A ship reported a peripheral pressure of 955 mbar (28.2 inHg),^[3] so a lower pressure was based on the small size of the hurricane. It quickly weakened over land, and it diminished to atropical storm on August 11. It dissipated over southwestern Mississippi on August 12 with fully tropical characteristics.^[2]

Many Last Island vacationers hoping to escape the approaching storm were awaiting the scheduled arrival of the shipStar, which provided regular service to the mainland. However, theStar was blown off course, barely escaping sailing into the open gulf, directly into the hurricane, where it would have almost certainly been lost. Passenger Tom Ellis, an experienced captain in local waters, and a few other passengers observed the ship was off course. Ellis alerted Captain Abe Smith, who corrected the course and barely making headway against the winds, managed to pull into the channel behind the hotel. TheStar was swept, crashing into shore and beached on the sand, where it stayed through the storm.^[5]

Visibility during the storm was extremely limited and eyes were blasted by sand until water covered the beaches. Sometime between 4:00 and 5:00 PM, the storm surge occurred suddenly, with the water rising several feet in a matter of minutes. Thestorm surge submerged the entire island and destroyed all of the buildings. The hotel, which held many women and children on the second floor and men on the first, collapsed, crushing many and sweeping others out to sea.^[5]

Several survivors managed to make their way to the hull of theStar. By tying himself with a rope to theStar, Captain Abe Smith was able to rescue at least 40 people from the storm surge.^[5] TheStar would serve as a shelter for the survivors until rescuers arrived three days later.

Many managed to survive by sheltering in or behind overturned cisterns, which were large wooden cylindrical tanks reinforced with iron hoops. Some clung to the raised foundations of the cisterns and a few to trees. A dozen people survived by clinging to a large piece of rotating playground equipment atop a levee.^[6] Many people floated on debris, including wall sections, logs and furniture. A sturdy wooden enclosure that held largeterrapins, a regional delicacy, provided enough protection to save several individuals. Another group survived by burying their feet in the sand and holding hands. Some survivors were carried to the marshes on the mainland, although some perished from injuries or lack of food and water.^[5]

Of the approximately 400 vacationers on the island, 198 were known or presumed dead and 203 were known survivors. Dixon (2009) provides lists of survivors and the dead.^[5]

Several of the victims wereenslaved people. Some of the enslaved people were credited with rescuing others, including several children.

The tragedy had a major impact on the planter society, which lost many members. At the time of the hurricane approximately two-thirds of the millionaires in the U.S. lived in Louisiana, many of those being plantation owners, especially sugar growers. Of the social group affected, many were friends, acquaintances, or related by marriage or known through business.

The family home of three of the Last Island casualties wasShadows-on-the-Teche inNew Iberia, Louisiana, now aNational Historic Landmark. Mrs. Frances Weeks (Magill) Pruett and her children Mary Ida Magill and Augustine Magill died in the natural disaster. The two children were buried in the plantation's cemetery.

The island itself was split into the Last Islands (Isles Dernieres).^[7] The island reportedly stayed submerged for several days before parts of it re-emerged as largesandbars. After the storm surge, the remains of theStar were the only sign that an island had ever existed there.^[7] Presently, the area is the Isles Dernieres Barrier Islands Refuge owned and managed by the Louisiana Department of Wildlife and Fisheries to provide protected nesting grounds for pelicans and other waterbirds.^[8]

The following are the numbers of deaths offshore:^[5]

SteamerNautilus: 85

SteamerManilla: 13

SchoonerEllen: 15

Other losses at sea: 20

On Calliou Island, which was located near Last Island, four homes were destroyed, and the others suffered substantial damage. Tides generated by the storm capsized two boats and swept awaystock.^[9] The city ofNew Orleans was inundated with 13.14 inches (334 mm) of rain. Every building inAbbeville was destroyed, includingSt. Mary Magdalen Church. Crops along theMermentau River suffered large losses from freshwater flooding. Farther east, storm surge and abnormally high tides left some sections ofPlaquemines Parish inundated by several feet of water, resulting in a near-total loss of rice crops. Severe losses to orange crops were reported in the area.^[7] Extensive damage occurred inSt. Tammany Parish atLewisburg,Mandeville, and other areas near theTchefuncte River. The storm swept away bathhouses and wharves, while also downing fences, trees, and vegetation.^[10]

The disaster became national news as soon as three survivors salvaged a small boat and sailed to the mainland for help.

In addition to the several firsthand accounts, the story of Last Island has been republished periodically. The list below includes only a few versions:

• In 1871,Harper's New Monthly had a story about the capsizing of the steamerNautilus and Jim Frisbee, the ship's second steward, the only survivor.
• Lafcadio Hearn's novelChita: A Memory of Last Island (1889), based on the Last Island hurricane of 1856, was a popular story when published; however, it either created or perpetuated several myths about the tragedy. One of the main sources of Hearn's novel was identified as the account written byIberville Parish sugar planter Michael Shlatre. After publication ofChita, Michael Shlatre's document became lost after being borrowed and not returned. The document was recovered during 1936, when it was found in the Iberville Parish courthouse inPlaquemine, La.
• Bill Dixon'sLast Days of Last Island (2009) was written using information from various archives in an attempt to be historically accurate. The numerous references include a newspaper article, a few books, and accounts of the survivors, many of whom are quoted.^[5]
