Lacombe's Connection To The American Revolution

 The Mississippi River played a significant part in the history of the United States, and a Lacombe area inventor helped developed the concept of steam-driven boats that made cargo transport on the river a reality. His early prototypes were designed at Oaklawn, one of the Lacombe area's most historic communities. 

Historian Don Sharp feels strongly that the contributions of inventor James Rumsey should be recognized as a major factor in helping the United States become an economic and political force. Rumsey, who once served as George Washington's Chief Engineer, was widely-recognized for his outstanding work, along with dozens of inventions over his lifetime.

Prior to steamships being able to go upstream against the current, the only river trade possible was the shipping of products downstream from the Midwest to New Orleans. And since boats could not return to their homeports up north, much of that cargo was brought in on rafts. After unloading their cargo, the rafts were dismantled and much of New Orleans was built using lumber salvaged from those rafts. 

But when steam propulsion of cargo ships became possible, cargo went both up and down the Mississippi. That achievement was the dreams of many inventors in the late 1700's, but James Rumsey of Lacombe demonstrated a successful method of steam propulsion on the Potomac River near Washington, D.C. It was the first time boat transport "against the current" was accomplished. 

A few years earlier, Rumsey, a mechanical engineer,  was working in his secret workshop off Bayou Lacombe, right across from the new Lacombe Nature Park north of Tammany Trace. Rumsey was designing a watercraft that could travel "against the current." And at the same time several men in Philadelphia were drafting a document, the Declaration of Independence, which would also go "against the current" of the existing government, which was an extension of the British monarchy on the other side of the Atlantic.

Rumsey's achievements helped solidify the new nation's ability to reach all up and down its rivers, spreading independence and freedom to all of its new citizens. 

The American Revolution that began on July 4, 1776, was accompanied by the another revolution in water transportation that began with Rumsey's steam-engine powered watercraft.

The reason why more people didn't know more about Rumsey's contributions to the revolution was that he, himself, was trying to keep it a secret. Based on the lack of a patent office to protect his invention, he had to keep many things secret, his background, his previous business failures, and his British connections. 

In a recent interview, Sharp told how Rumsey's invention efforts were concurrent with the American Founding Fathers who were inventing a new form of government. He tells how the industrial revolution joined forces with the American Revolution, and a nation was born that the world had never seen before. 

He hopes that some kind of historical marker will be placed in the Lacombe Nature Park or across the bayou at Rouville and Oaklawn streets to mark where Rumsey did his early work on his boat. 

Sharp feels that the key role that Rumsey played in American history needs to be recognized locally as it is already recognized with a historical marker in Shepherdstown, West Virginia. 

"Rumsey is so important," Sharp says." He started a revolution in water transportation, and he helped settle mid-America. He was a friend of Thomas Jefferson and Benjamin Franklin. He died in 1798." 

A historical marker about the end of the American Revolution is already in place at the Madisonville town hall, where Capt. Shaw declared that "we are all Americans now."

James Rumsey Overview

 Historian Don Sharp recently re-emphasized the importance of Lacombe area resident James Rumsey and his contributions to the founding American republic. Rumsey was friends with Benjamin Franklin and Thomas Jefferson, served as George Washington's Chief Engineer, and contributed much to the prosperity of the young country by inventing steam-engine propelled watercraft. That was a discovery that only a few years later led to steamboats carrying cargo up and down the Mississippi River, opening up the vast Midwest to settlement.

While much is known about the last 12 years of Rumsey's life, Don Sharp has discovered a wealth of information about Rumsey's early life, how he was born in Bristol, England, how he fought in the French and Indian Wars, and how he ran a pioneer trading post in Illinois before coming down through Natchez, then to New Orleans, and finally to Lacombe in St. Tammany Parish. At that time this area was part of British West Florida, which has now become known as "The Fourteenth Colony."

Sharp's research helps correct some of the misinformation that had been given out regarding Rumsey's early life, and Sharp even explained why the misinformation was formulated in the first place by persons wishing to protect his legacy. 

Rumsey, working in secret in Lacombe, explored various ways in which the newly-invented steam engine could be used to propel boats upstream against the current, which was a major problem at the time. To keep his secret designs safe, he moved from Lacombe to Pearl River Island at the mouth of the Pearl River. One of his visitors there was William Bartram, a noted botanist, who stayed with Rumsey for a month while recovering from an illness. Even Bartram, in the account of his travels, was unable to figure out what Rumsey was working on in secret. 

When the American Revolution broke out, St. Tammany was a British colony subject to attacks, so with the help of some high-ranking Louisiana politicians, Rumsey was able to re-locate to Baltimore, MD. That is where he perfected his steam-propelled watercraft, demonstrating it to the public for the very first time on the Potomac River in Shepherdstown, Virginia, in 1787.

Ten years later, Benjamin Franklin formed The Rumserian Society to honor the inventor and study his discoveries.

Part Two - James Rumsey's Life

James Rumsey, the inventor of the steamboat, lived on Bayou Lacombe for a few years, but Don Sharp found out that Rumsey spent four years in England after his successful test run of his steamboat on the Potomac River in 1787 at Shepherdstown, West Virginia. There is even documentation that James Watt and Matthew Boulton, inventors of the steam engine, wanted Rumsey to join with them on developing uses for the invention.

Rumsey's friendship with American inventor Benjamin Franklin prevented him from taking them up on that offer, apparently. Rumsey knew George Washington (he worked for him) and Thomas Jefferson well, so he became quite well-known in early American scientific circles after he finished his work on Bayou Lacombe and Pearl River Island. The Lake Pontchartrain Basin Maritime Museum in Madisonville has a great exhibit talking about James Rumsey and his many inventive contributions.

Here's a picture of a statue of the three top steam engine inventors, as erected in Birmingham, England, James Watt, Matthew Bolton and William Murdoch.
