British forces. He participated in the Battle of Brownstown on August 5, 1812 and the Battle of Maguaga on August 9. After this battle, Tecumseh presented Roundhead with a sash given to him by General Isaac Brock, as Tecumseh claimed it should belong to an older and more skilled warrior. Roundhead did not wear the honorable sash, as he did not want to cause jealously among the other war chiefs. A few days later, he helped in the capture of Fort Detroit during the Siege of Detroit on August 15. He then joined up with Major Adam Muir for the British occupation of Fort Miami along the Maumee River in September 1812. He later fought in the Siege of Fort Meigs from April 28–May 9, 1813. Another of Roundhead's brothers, Jean-Baptiste, died during this failed siege. Roundhead's most notable accomplishment during the War of 1812 took place when he fought in the Second Battle of the River Raisin on January 22, 1813, overwhelmingly defeating the Americans. Tecumseh, who did not participate in the battle, gave command of the native forces to Roundhead, who was aided by fellow Wyandot chief Walk-in-the-Water. They commanded approximately 800 Native Americans along with Henry Procter's 597 British troops against a force of 1,000 Americans. The battle was a disastrous defeat for the Americans, as they were caught off guard in the early hours of the morning; it resulted in the most American casualties of any battle of the War of 1812. Shortly into the battle, Roundhead captured ill-prepared American general James Winchester and stripped him of his uniform, leading to the legend that Winchester was captured in his nightshirt. Having been captured, Winchester was unable to command his troops, and they suffered heavy losses. Roundhead presented Winchester to Procter, who forced the general to surrender his army after a few hours of fighting. Forty percent of his men had been killed; another 547 were taken prisoner at surrender. Following the battle, Roundhead aided in the quick retreat of Procter's troops back into Upper Canada. Months later, Tecumseh met American opposition there at the Battle of the Thames. Death Roundhead died of natural causes shortly before the Battle of the Thames on October 5, 1813. On Roundhead's death, General Procter wrote in a letter dated October 23, 1813, "The Indian cause and ours experienced a serious loss in the death of Round Head." For years, Roundhead,
