Merritweather is a fascinating book about a remarkable and heroic person. The author does a great job in capturing Lewis’s heroic endeavors as well as his tragic personality disorders. He also offers a great account of Jefferson’s mentorship of his protégé and then his abandonment and lack of understanding at the end of Lewis’s life. Lewis was a visionary, a superb outdoorsman, naturalist, hunter, inventor, and geographer. He spent his entire life searching for the perfect wife without success. His dynamic and compelling nature attracted women and his neediness drove them away. His planning and leadership of the Corps of Discovery was outstanding. By recruiting the resourceful Will Clark to be his co-captain on the adventure, he ensured its success. He successfully engaged numerous Indian tribes who (mostly) helped him enthusiastically to make his journey a success. He followed the Missouri to its source expecting to find an easy passage across the Rocky Mountains which Jefferson had described as probably like the gentle Appalachians. They proved to be more like the Alps and the corps spent weeks of cold and starvation in crossing them to the Pacific side, aided by their Indian guide Toby and their Shoshone team member, Sacagawea, who was one of the most important and impactful members of the expedition. Lewis was an inspiring leader who had his team vote on the most important decisions, treating all as equal partners, including the slave York and Sacagawea. Lewis was a tragic figure from Shakespeare who knew his demons of melancholy, alcohol, and opium but was never able to overcome them. His tenure as the governor of the Louisiana Territory was marked by politics and squabbling and gave him no satisfaction. His sad ending could have been avoided if he was able to have the right women as a partner. It’s ironic that he once did find this partner early in life but they were unable to agree to a life together because of his ambition to spend years finding the NW passage to the Pacific.
