Frederic Remington crafted this scene of bloody confrontation for white audiences east of the Mississippi River, who imagined the West as a place of both danger and opportunity. An unseen Sioux warrior has shot a cavalry scout, who slumps over his horse while the troops behind him flee the ambush. A sculptor and illustrator as well as a painter, Remington was famous for his dynamic compositions of frontier life, which presented mythologized views of encounters between Native and settler-colonial communities in tantalizing color and detail. Although he traveled to western locations to sketch or gather material on assignment, he executed most of his work in his New York studio, including The Advance-Guard, which was later reproduced in Harper’s Weekly alongside an article by the artist.
