In historical context, what does the term 'Last Stand' refer to in relation to Custer?

The term 'Last Stand' in relation to Custer specifically refers to the Battle of Little Bighorn in 1876, where General George Armstrong Custer and his troops faced a decisive defeat against a coalition of Native American tribes, primarily the Lakota Sioux and Cheyenne. Custer's plan to engage and defeat the Native forces was based on flawed intelligence and underestimating the size and preparedness of the opposing forces. The battle resulted in the complete annihilation of Custer's battalion, marking one of the most significant and symbolic defeats for the United States military during the Indian Wars. This event has since been remembered as Custer's "Last Stand," highlighting the dramatic end of his military career and illustrating the broader context of conflict between Native Americans and U.S. forces during this period of American history.
