Lieutenant Zebulon M. Pike, exploring the Upper Mississippi territory included in the recent Louisiana Purchase, arrives at the North West Company post on Gaa-zagaskwaajimekaag (Leech Lake). Incensed that the British Union Jack still flies there, he orders it shot down and replaced with the Stars and Stripes. Pike was something of an ingrate, however, as he enjoyed the hospitality of the post both before and after the incident. British fur traders remained in the region until the end of the War of 1812.
