The first and only female Buffalo Soldier joined the Army disguised as a man

Before women were allowed to join the military, Cathay Williams decided that she wouldn't let her gender, or the color of her skin, get in the way of her ambitions. She became the first known African American woman in American history to join the armed forces by disguising herself as a man.

Williams was born into slavery in the year 1842 in Independence, Mo. She was a house slave for William Johnson, a planter in Jefferson City, Mo. During the beginning of the Civil War, Williams was claimed to have been "freed" by Union soldiers, but was forced to work for the Federal Army as a paid cook and laundress.

During her time serving in the Federal Army, she gained an insight into military life by answering directly to two Union Generals, one of whom was General Philip Sheridan. After the war ended, Williams did not have the means of supporting herself, but she wasn't about to let her newly garnered freedom get snuffed out like a flame.

In November 1866, Williams disguised herself as a man and enlisted in the U.S. Army as William Cathay. Full-on medical exams weren't mandatory at the time, and Williams was able to pas a quick, general health check before filing in among the ranks.

She was found fit for duty and assigned to the 38th U.S. Infantry, Company A, an all-black regiment in St. Louis, Mo. which, eventually, became a part of the renowned Buffalo Soldiers. Apparently, the only two people knew her secret — a friend and a cousin — both of whom served alongside her in the same regiment. They never divulged her charade.

Williams traveled with her regiment and helped protect miners and immigrants from Apache attacks at Fort Cummings, Mo. Unfortunately, military service took its toll on Williams. She was in and out of the hospital for most of her service due to neuralgia (pain caused by a pinched nerve). Surprisingly, it was six months after her first hospitalization when they found out that she was a woman.

After the truth was revealed, Williams was discharged from the Army honorably on October 14, 1868. Little of her life is known after she was discharged, except for her attempts to get a pension for the disabilities that she incurred from military service.

Sadly, Williams never received compensation for her medical issues. The Pension Bureau claimed her illnesses were pre-existing and, because she was a woman, her service was not considered legal, disqualifying her from pension pay.

She may not have intended to become a prominent figure in history, but one thing is for sure, Cathay Williams will forever be regarded as the first and only female Buffalo Soldier to have served in the U.S. Army.
