Who were the leaders of the lewis and clark expedition besides lewis and clark?

hope this helps could not find any other leaders but found this: The Lewis and Clark Expedition began in 1804, when President Thomas Jefferson tasked Meriwether Lewis with exploring lands west of the Mississippi River that comprised the Louisiana Purchase. Lewis chose William Clark as his co-leader for the mission.

There were no other leaders in the Lewis and Clark expidition please tell me if I am wrong because I am curious if there were more leaders thanks :)

can you post options?

in 1897, pershing became a tactical officer at west point, and that's where he was given the nickname "black jack." pershing's first name is "john," for which "jack" is a nickname, and he was a white man who commanded black troops. hence "black jack".
