Exploration 19th Century North America

Lewis and Clark First Sight Rocky Mountains

The Lewis and Clark Expedition had traveled up the Missouri River for more than a year seeking a water route to the Pacific. On May 26, 1805, Meriwether Lewis climbed bluffs near the river in present-day Montana and glimpsed distant snow-capped peaks of the Rockies. Clark had noted similar distant features earlier that day. The sighting confirmed that the mountains formed a formidable barrier far taller and more extensive than anticipated, dashing hopes of an easy portage between river systems. The Corps of Discovery pressed onward, later navigating the difficult terrain and rivers that followed.

Nelson Victorious at Battle of Trafalgar

The Napoleonic Wars pitted Britain against a Franco-Spanish alliance seeking naval supremacy to support an invasion of England. British Admiral Horatio Nelson commanded a fleet of 27 ships blockading the enemy at Cádiz, Spain. On October 21, 1805, the combined French and Spanish force of 33 ships sortied, leading to a chaotic engagement off Cape Trafalgar. Nelson's innovative tactics of breaking the enemy line in two columns allowed superior British gunnery to prevail despite being outnumbered. Nelson was mortally wounded aboard HMS Victory, but the victory shattered Napoleon's naval ambitions and secured British command of the seas for the war's remainder.

Lewis and Clark Expedition Sights Pacific Ocean

The Lewis and Clark Expedition, commissioned by President Thomas Jefferson after the Louisiana Purchase, aimed to explore the American West, map routes to the Pacific, and establish U.S. claims. After traversing the Rocky Mountains and navigating the Columbia River system through challenging terrain and weather, the Corps of Discovery reached the river's estuary. On November 7, 1805, William Clark recorded in his journal the sighting of what they believed was the Pacific Ocean, exclaiming 'O! the joy.' The party spent the following weeks exploring the area amid rain and tides before establishing winter quarters at Fort Clatsop.
