The question refers to U.S. military history, focusing on the roles of several leaders during early American wars. It touches on General William Henry Harrison's military successes, General Edward Braddock's defeat during the French and Indian War, and General George Washington's leadership during the Revolutionary War.
Step-by-step explanation:
The original question seems to be a mix-up about historical figures and their roles, but based on the provided references, the subject is related to several U.S. military and political leaders and their involvement in early American history. Benjamin Harrison was actually a President of the United States, and the mention of the 70th Indiana Regiment instead refers to Benjamin Harrison's involvement in the Civil War, not the Revolutionary War or the War of 1812. Within the context of the references, we see that the focus is on the military history surrounding the early years of the United States, with significant emphasis on the Revolutionary War and the War of 1812.
For example, General William Henry Harrison, who later became a president, was celebrated as a war hero in the 1840 presidential campaign for his military service against Shawnee chief Tecumseh at the Battle of Tippecanoe in 1811. His success in the military earned him fame and contributed to the popular campaign slogan 'Tippecanoe and Tyler too'.
In contrast, General Edward Braddock's military actions are recounted from the period of the French and Indian War. He assumed supreme command over British and colonial forces following the enactment of the Plan of Union. Sadly, his first significant military campaign ended in disaster at the Battle of the Monongahela near Fort Duquesne, marking one of the earliest major setbacks for British forces during the conflict.
While General George Washington famously led American forces as commander-in-chief during the Revolutionary War, his leadership was tested early on in battles around New York, such as the Battle of Long Island and the Battle of Harlem Heights. His strategic retreats and continued resistance would eventually contribute to the American triumph in the war for independence.
