How did Sacagawae help Lewis and clark?

Answer 1

She became invaluable as a guide in the region of her birth, near the Three Forks of the Missouri, and as a interpreter between the expedition and her tribe when the expedition reached that area. After she gave birth during the expedition to Jean-Baptiste Charbonneau on February 11, 1805, she also quieted the fears of other Native Americans, for no war party traveled with a woman and a small baby. She was able to translate when they met up with Shoshone-speaking Indians. She told them about some of the geography and any various animals and plants that she was familiar with.

She had been kidnapped from her own tribe and spent many years as a slave or prisoner of another Indian tribe. Once she travelled back to her own native tribal lands with Lewis and Clark, she was able to see her family for the first time in many years. It is important to remember that the entire expedition improvised practically everything as they went along, and Sacajawea and her recruitment for translating were no exception. They were (other than Sacajawea) going into the unknown, and so were entirely unprepared for many things they tried to do.

Answer 2

She helped them with reading compasses and helping speak the native languages.
