United States Army Corps of Topographical Engineers


The U.S. Army Corps of Topographical Engineers was a branch of the United States Army authorized on 4 July 1838. It consisted only of officers who were handpicked from West Point and was used for mapping and the design and construction of federal civil works such as lighthouses and other coastal fortifications and navigational routes. Members included such officers as George Meade, John C. Frémont and Stephen Long. It was merged with the United States Army Corps of Engineers on 31 March 1863, at which point the Corps of Engineers also assumed the Lakes Survey for the Great Lakes. In the mid-19th century, Corps of Engineers' officers ran Lighthouse Districts in tandem with U.S. Naval officers.
In 1841, Congress created the Lake Survey. The Survey, based in Detroit, Mich., was charged with conducting a hydrographical survey of the Northern and Northwestern Lakes and preparing and publishing nautical charts and other navigation aids. The Lake Survey published its first charts in 1852.

Major expeditions prior to the Corps' creation

In all, there were six major expeditions into the Louisiana Purchase, the first being the best known Corps of Discovery led by Lewis and Clark in 1804-1806. A second expedition in 1804 included astronomer and naturalist John Dunbar and prominent Philadelphia chemist William Hunter. This expedition attempted to follow the Red River to its source in Texas, then controlled by Spain, but turned back after three months.
In April 1806 a second Red River Expedition was led by Captain Richard Sparks and included astronomer and surveyor Thomas Freeman and Peter Custis, a University of Pennsylvania medical student who served as the expedition's botanist. The group of 24 traveled 615 miles up the Red River before being turned back by Spanish authorities. President Thomas Jefferson hoped that this expedition would be nearly as important as the one led by Lewis and Clark, but the interruption by Spanish authorities prevented this hope from being realized.
In 1805–1806, Lieutenant Zebulon Pike was ordered by General James Wilkinson, Governor of the Upper Louisiana Territory, to find the source of the Mississippi River.
In 1806–1807, President Jefferson ordered Lieutenant Pike, on another expedition, to find the headwaters of the Arkansas River and Red River. This is better known as the Pike Expedition. Spanish forces arrested Pike and confiscated his papers, but assigned a translator and cartographer to translate Pike's documents.
In 1817 Major Stephen H. Long explored the upper Mississippi River, selecting sites for Fort Smith on the Arkansas River and Fort St. Anthony at the confluence of the Minnesota and Mississippi.
In 1819, President James Monroe and Secretary of War John C. Calhoun ordered General Henry Atkinson to lead what became known as the Yellowstone Expedition. One objective was to eliminate British influence among the Native American tribes in the region. Nearly 1,000 soldiers were transported by five steamboats up the Missouri River to the Mandan villages at the mouth of the Yellowstone, where they built a fort. This was the first known use of steam propulsion in the west.
