Little is known about Benjamin Edwards. He was a member of the Stephen Harriman Long Expedition in charge of scientific explorations between the Mississippi River and the Rocky Mountains. Long designed and supervised the construction of a steamboat, the Western Engineer, that was to carry the scientific team, that included William Baldwim, Titian R. Peale, Thomas Say, and Samuel Seymour, up the Mississippi River. Shortly after commencing the journey on 5 May 1819, the expedition encountered problems with the steamboats design and machinery, a lack of efficient fuel, and the muddy waters of the Missouri River, all of which slowed progress.
On 17 September the steamboat arrived as Fort Lisa, a trading fort of the Missouri Fur Company about five miles below Council Bluffs. The Long expedition selected a spot between Fort Lisa and Council Bluff to establish "Engineer Cantonment", their winter quarters. After a few months the Cantonment was completed and Major Long returned to the east coast. He returned the following May with orders from the War Department to cease work along the Missouri and turn instead to exploring the Platte River and its sources. The expediton left their winter quarters on 6 June 1820.
Whether Edwards joined this expedition or not is unknown. By August 1822 he had left government service and found employment on the steamboat Hope in New Orleans. Always hoping to go home to his family in Wear, New Hampshire, Edwards continued to anticipate that he would receive the $850 dollars owed to him by the U.S. Government for is services on the Long expedition that would enable him to return to New Hampshire. While waiting, Edwards was employed at a sawmill in Alexandria, Louisiana, where he oversaw slaves. By 1827 the money had still not arrived and feeling that it never would, Edwards settled in New Orleans.
