Happy Departure Day!

May 14 marks the anniversary of the start of the Lewis & Clark Expedition in 1804. Spanning almost two and a half years and thousands of miles, the Expedition sought to find a route to the Pacific Ocean, make maps of the newly purchased Louisiana Territory, document flora and fauna, and meet with the many Native American nations along the way.

The party had prepared all winter at Camp River Dubois. Now was the start of the test of their soldiers' skills and the preparation of supplies. Excitement, anxiety, curiosity, and uncertainty were likely a sampling of the swirling emotions amongst the Detachment. From Captain Clark's perspective, excitement was the prevalent emotion. He described the soldiers as being in "high Spirits."

William Clark's Entry for May 14, 1804:

"Set out from Camp River a Dubois at 4 oClock P. M. and proceded up the Missouris under Sail to the first Island in the Missouri and Camped on the upper point opposit a Creek on the South Side below a ledge of limestone rock Called Colewater, made 4½ miles, the Party Consisted of 2, Self one frenchman and 22 Men in the Boat of 20 ores, 1 Serjt. & 7 french in a large Perogue, a Corp and 6 Soldiers in a large Perogue. a Cloudy rainey day. wind from the N E. men in high Spirits"

in 1804

The young soldiers were anxious; spring had arrived at Camp River Dubois, where the small Wood River entered the great Mississippi. It was April and there was talk about shoving off by April 18, 1804. Meriwether Lewis thought otherwise – more supplies were needed from St. Louis, and he was still collecting information from traders and trappers who had already traveled large sections of the Upper Missouri.

William Clark, who was with the Corps at the camp, struggled holding the men back and keeping them focused. So, on May 7, he had them load the keeled boat and the next day a group of 20 soldiers took it for a test run on the Mississippi to make sure it was well-balanced and stable.

On May 11, George Drouillard brought seven French voyageurs whom he recruited in St. Louis to the camp and on Sunday, May 13, Clark sent a brief letter down to St. Louis advising Lewis that everything was loaded and the Corps was ready for departure.

At last, in the morning of Monday, May 14, Clark wrote, “a Cloudy morning fixing for a Start.” The designated departure time of four o’clock finally arrived, and one keeled boat with 26 soldiers aboard, a pirogue with seven men, and another canoe paddled by eight voyageurs crossed over the Mississippi and entered the mouth of the Missouri. A group of locals stood along the Mississippi's banks and wished their winter visitors a fond farewell.

Clark intended to travel just six miles upstream before sunset, but a suitable island at four miles became the first campsite on the Missouri. This short journey was a test known as a “Hudson's Bay Start.” Often used by trappers and traders, a HBS was a short, lower risk launch to make sure everything was in order, and if not, the origination point wouldn't be far away.

The years of planning, training, packing, and dreaming were over. The adventure of the Expedition was underway!
