Ambrose roams the country's history, praising the men and women who made it exceptional. He considers Jefferson and Washington, who were progressive thinkers (while living a contradiction as slaveholders), and celebrates Lincoln and Roosevelt. He recounts Andrew Jackson's stunning defeat of a superior British force in the battle of New Orleans with a ragtag army in the War of 1812. He brings to life Lewis and Clark's grueling journey across the wilderness and the building of the railroad that joined the nation coast to coast. Taking swings at political correctness, as well as his own early biases, Ambrose grapples with the country's historic sins of racism; its ill treatment of Native Americans; and its tragic errors such as the war in Vietnam, which he ardently opposed. He contrasts the modern presidencies of Eisenhower, Kennedy, Nixon, and Johnson. He considers women's and civil rights, immigration, philanthropy, and nation building. Most powerfully, in this final volume, Ambrose offers an accolade to the historian's mighty calling.
