LC, the Post Office Oak is just a little west of the Council Oak, and is another covered tree trunk like the Council Oak, it stood in front of the old brewery. Why they built the Brewery right on top of it is strange, when alive it stood on the left side of the staircase by the porch. The Kaw and the Cheyenne had long been enemies, and in an altercation with the Kaw, in which the Cheyenne took offence had occured near Fort Zarah (now Great Bend) to the west along the trail. On June 1, 1868, about one hundred Cheyenne warriors descended on the Kaw reservation, about three miles to the southeast of town. Terrified white settlers took refuge in Council Grove. By some acounts the Cheyenne rode through Council Grove on their way out to the Kaw Reservation. The Kaw men painted their faces, donned their finery, and sallied forth on horseback to meet the Cheyenne. The two Indian armies put on a military pageant featuring horsemanship, fearsome howls and curses, and volleys of bullets and arrows. After four hours, the Cheyenne retired with a few stolen horses and a peace offering of coffee and sugar by the Council Grove merchants. Nobody was hurt on either side. They say many folks from Council Grove rode out and watched the battle from the hills above. The Brewery marker. During the battle, the mixed-blood Kaw interpreter, Joseph James Jr (more commonly known as Jojim or Joe Jim) galloped 60 miles to Topeka to request assistance from the Governor. Riding along with Jojim was an eight-year old, part- Kaw Indian boy named Charles Curtis or “Indian Charley.” Curtis would later become a jockey, a lawyer, a politician, and Vice President of the United States under Herbert Hoover. The highest office ever held by a person of Native American Heritage. Charles Curtis was born January 25, 1860, in Topeka, Kansas, to Oren Arms and Ellen (Pappan) Curtis. He spent his earliest years partly in the white and partly in the Native American community, he spoke Kaw and French before he learned to speak English. The son of Orren Curtis, a white man, and Ellen Pappan, who was one-quarter Kaw Indian, Charles Curtis on his mother's side was the great-great grandson of White Plume, a Kansa-Kaw chief who had offered assistance to the Lewis and Clark expedition in 1804. White Plume's daughter married Louis Gonville, a French-Canadian fur trader, and their daughter, Julie Gonville, married Louis Pappan. Curtis’ mother died when he was three and his early life was spent with his maternal grandmother and other relatives on the Kaw Indian Reservation near Council Grove. Life was unsettled on the reservation. Due to conflicts among the Kaws, Cheyennes, and Arapahos, young Curtis was sent to Topeka in 1868 to live with his paternal grandmother. <SUP id=cite_ref-20 class=reference></SUP> Believed to have been 270 years old when it died in 1990, this bur oak is said to have served as an unofficial post office for travelers on the Santa Fe Trail from 1825-1847. Passing caravans could leave messages for future travelers in a cache in the base of the tree.
