SUBMITTED — The Alabama Historical Commission (AHC), in coordination with the National Park Service (NPS), the Smithsonian National Museum of African American History and Culture, (NMAAHC), and SEARCH, Inc., has completed the investigation of the shipwreck remains discovered in January 2018 in Baldwin County, Alabama.
In collaboration with the Washington-DC based Slave Wrecks Project, (SWP), one goal of the study was to determine if the vessel is, in fact, the Clotilda, the last known ship to bring enslaved Africans to the United States. The team, composed of experts from SEARCH, NPS, SWP, and the University of West Florida, examined and documented the Twelvemile Island Wreck Site on March 1-2, at the request of and under the supervision of the Alabama Historical Commission.
This team of experts employed high precision GPS, total station, photodocumentation, and measured drawings as well as field observations. The work was done through scuba diving, limited hand excavation and shallow water archaeological inspection. Wood samples were collected from a variety of exposed areas on the wreck. This work was completed under a permit from the Alabama Historical Commission and the U.S. Army Corps of Engineers.
Before the team deployed, detailed historical and archival research into the construction and history of the Clotilda. Based on this research the wreck of the Clotilda is in this area of the Mobile River. Based on preliminary research and two days of field work, we are confident that this wreck is not the Clotilda for the following reasons:
• Clotilda was 86 feet long while the length of the Twelvemile Island Wreck is 158 feet, 5 inches The interior “depth” inside Clotilda was 6 feet, 11 inches while the interior depth of the Twelvemile Island Wreck is too deeply buried in the mud to measure completely but is at least 10 feet deep based on the amount of the bow structure remaining onsite.
• The size of timbers on the wreck is larger than those that were used to build a vessel the size of Clotilda. For example, the frames, or “ribs,” are 10 by 10 inches and the hull planks are 2 inches thick. Clotilda would have frames 2 inches smaller and planks ½ inch thinner.
• Clotilda had 2 masts. The size of the Twelvemile Island Wreck is too large for a 2 masted rig, which originally had 3 masts.
• The Twelvemile Island Wreck has flat iron reinforcing the hull, which is commonly found on larger wooden vessels built from the 1850s through the early 1920s. This timeframe is after the construction of Clotilda.
• While the wood samples have not yet been analyzed, all of the wood observed on the Twelvemile Island Wreck appears to be soft wood such as pine. Clotilda was built with oak and yellow pine. There was no oak observed on the Twelvemile Island Wreck.
• A large portion of the upper bow of the Twelvemile Island Wreck is buried in mud on the shoreline. The condition of the wood indicates this wreck was largely an intact vessel that was abandoned on the shore. It slowly deteriorated with marine organisms eating the wood above the mud until heavier parts of the hull collapsed.
• Clotilda was burned and then sank. There is no definitive evidence of burning on the Twelvemile Island Wreck. The damage from small marine organisms that eat wood can look similar to fire damage. Our team excavated part of the site to expose areas of the ship to examine the damage. Undamaged sections of the wreck show the damage was confined to the waterline area only, whereas a fire would have damaged or destroyed the hull above the waterline.
In summary, the Twelvemile Island Wreck is too long, the timbers are too large, timber known to have been used to build Clotilda was not seen, and the there is no definitive evidence for burning.
“The discovery and first examination of the wreck by Ben Raines and our colleagues at the University of West Florida and the media stories that followed have powerfully reconnected the story of Clotilda to a national and international audience,” said Lisa D. Jones, Executive Director of the AHC. “It shares a story with profound meaning in Alabama, and especially to the descendant community of Africatown. While the follow up investigation of the Twelvemile Island Wreck has found that this wreck is not Clotilda, its discovery and the attention paid to it will be the start of a renewed effort to find Clotilda.”
“Further historical research and field investigation we have done suggest that many wrecks lie in this part of the Mobile River,” said James P. Delgado, PhD, Senior Vice President, SEARCH, Inc. “We believe that a comprehensive survey of the area with a range of modern technology, followed by an examination of each wreck encountered by knowledgeable professionals will be the best means to find the physical remains of Clotilda. The archaeological team will continue to make ourselves available to answer questions from the community of Africatown and the citizens of Alabama.”
“We would like to express our deep appreciation to the Alabama Historical Commission, the community of Africatown and the many individuals and groups who made it possible for our team to work on this important project, said David L. Conlin, PhD, National Park Service, Submerged Resources. “Finally, we would like to acknowledge the Smithsonian National Museum of African American History and Culture and the Slave Wrecks Project for their support of this work.”
There is an informational meeting scheduled for Monday, March 5 at 10 a.m. at the Community Meeting at the James L. Hope Community Center (850 Edwards St., Mobile).
