SHREVEPORT, La. -- Civil War submarines known to once be in Shreveport but unseen since that conflict continue to elude searchers.
"The submarines look like they will stay an enigma for a while," said Ralph Wilbanks, the diver who led underwater efforts that found the Confederate submersible Hunley off Charleston Harbor in 1995. "We have looked in the bayou and we didn't see anything we didn't see last time."
Wilbanks, together with fellow Hunley discoverer Harry Pecorelli III and diver Darrell Taylor, spent the last week in February in Shreveport, dragging side-scan sonars and magnetometers in countless lanes on mapped grids on the Red River, Cross Bayou and Cross Lake, looking for nagging mysteries from the Civil War to World War II.
As with Wilbanks' first visit to Shreveport in 1999, the current survey was underwritten by best-selling author Clive Cussler and his nonprofit, volunteer National Underwater and Marine Agency. Cussler said his decision to send Wilbanks and his crew back to Shreveport was based on "new data where the river changed course ... Apparently nothing was found again."
Wilbanks thinks the submarines were abandoned and salvaged after the Civil War.
"I think it's reasonable to think they may have just melted (them) back down and made steel out of (them)," he said.
Wilbanks and his crew also made scanning runs over the site of the suspected grave of the Civil War warship Grand Duke, out in the middle of Red River just north of Cross Bayou.
They got some hits there but results were inconclusive, with the sources of strong magnetometer readings under tree stumps and driftwood.
"There are some targets in the river and some very strong targets on the Bossier side," said Shreveport cartographer and historian Gary Joiner. "Some of the targets in the river are currently protruding above the channel floor a few feet. The Bossier side is currently very shallow in this area and we could not get the instruments near it."
While there, Wilbanks decided to spend a few days scanning Cross Lake to try to find a World War II B-26 bomber long rumored to have belly landed and sunk into the muck.
"We decided, since we were coming all the way out here, we'd look for this plane, too," Wilbanks said.
"Finding what you're looking for, that's the most exciting part," said Pecorelli, who's worked with Wilbanks since the mid-1990s.
"Most of the time you find out where things aren't," Wilbanks said. "You very seldom find where things are. The other thing is, you either find it in the first lane or the last lane."
Precedent has shown that these historic treasures do exist and are just waiting to be found.
Several decades ago, a fisherman on the Red River noticed something sticking out of a crumbling bluff. It turned out to be a dugout canoe, several millennia old, and one of the area's richest historical finds.
Known wrecks of Civil War-era vessels include the transport Kentucky, just south of LSU-Shreveport, and the Union ironclad Eastport, near Montgomery.
Even though the recent survey didn't turn up the subs or the airplane, it has increased the store of knowledge of the Red River and its tributaries.
For years, Joiner has thought the submarines might have been scuttled in an area near the old Battery Walker, which is now under dry land at what Bossier City calls Cane's Landing.
Using ground-penetrating radar might be the next step, he said, but that area was used as a dump for many years, and items from the intervening 14 decades would shield the Civil War material from detection.
These searches are tremendously important in terms of adding to the store of history, Joiner said.
"We are practicing forensic history. We are using the best technology available today in this research. We are working with some of the best known researchers in the world .... Shreveport is, at this time, one of the focal points for this advanced research because it was important during the Civil War and the research and development then might exist today."
