The St. Vrain massacre was an incident in the Black Hawk War. It occurred near present-day Pearl City, Illinois, in Kellogg's Grove, on May 24, 1832. The massacre was most likely committed by Ho-Chunk warriors who were unaffiliated with Black Hawk's band of warriors. It is also unlikely that the group of Ho-Chunk had the sanction of their nation. Killed in the massacre were United States Indian Agent Felix St. Vrain and three of his companions. Some accounts reported that St. Vrain's body was mutilated. St. Vrain and his party were attacked while en route from Dixon's Ferry, Illinois (now Dixon) to Galena, Illinois. St. Vrain had been ordered by General Henry Atkinson to deliver dispatches to Fort Armstrong. Colonel Henry Dodge's men interred the remains of St. Vrain and his companions after the massacre.

The Battle of Kellogg's Grove is either of two minor battles, or skirmishes, fought during the Black Hawk War in the U.S. state of Illinois, in present-day Stephenson County at and near Kellogg's Grove. In the first skirmish, also known as the Battle of Burr Oak Grove, on June 16, 1832, Illinois militia forces fought against a band of at least 80 Native Americans. During the battle, three militia men under the command of Adam W. Snyder were killed in action. The second battle occurred nine days later when a larger Sauk and Fox band, under the command of Black Hawk, attacked Major John Dement's detachment and killed five militia men. The second battle is known for playing a role in Abraham Lincoln's short career in the Illinois militia. He was part of a relief company sent to the grove on June 26 and he helped bury the dead. He made a statement about the incident years later which was recollected in Carl Sandburg's writing, among others. Sources conflict about who actually won the battle; it has been called a "rout" for both sides. The battle was the last on Illinois soil during the Black Hawk War.

Kellogg's Grove is an area in western Stephenson County, Illinois, United States near the present-day unincorporated town of Kent. The grove is considered historically significant because it was the site of two minor skirmishes during the Black Hawk War in 1832. Today, most of the grove is privately owned but 1.5 acres (6,100 m2) are allocated as a park owned by Stephenson County. While most of the battle occurred on what is today private property the park contains a monument dedicated to the battle and cemetery with the graves of several militia members killed during the skirmish at Kellogg's Grove. The cemetery also holds the graves of those killed in other area battles. The Kellogg's Grove battle site was added to the U.S. National Register of Historic Places in 1978.
