At the Patit Creek campsite, members of the Corps carried out the ordinary work of camp life while each person filled a distinct role. William E. Bratton, a blacksmith, gunsmith, skilled hunter, plant forager, and messenger, rested with a bad back. Jean Baptiste Charbonneau, called Pompey or Pomp, was the son of Sacagawea and Toussaint Charbonneau. Toussaint Charbonneau served as interpreter, camp tender, and cook, and the captains were fond of his boudin blanc cooking. Captain William Clark kept a journal, took celestial readings, and made maps while giving orders to his servant York. Hunters, woodsmen, cooks, interpreters, traders, boatmen, and camp tenders worked throughout the camp: fires were started and tended, wood and water were brought in, meat was handed out for cooking, guns and gear were repaired, pack bags were sorted, a white stallion was held and hobbled, dogs were collected and herded, and several men came in from hunting. Captain Meriwether Lewis, a journalist, medic, and botanist, ate cow parsnip as an Indian guide from Chief Yellept's camp showed him how to peel and eat it. Sacagawea, an interpreter, camp tender, cook, gatherer, and mother of Pomp, hung a cradle board on a tent pole. Seaman, Captain Lewis's Newfoundland dog, was with the party, and three Indians who had joined the Corps the day before communicated with George Drouillard.
