He is known for having been forced into retirement due to health concerns before the start of World War I and later riding from Wilberforce, Ohio, to Washington, D.C. to prove his physical fitness for duty.

In March of 2013, President Obama designated Colonel Charles Young's house in Wilberforce a national monument, but it is not yet open to visitors. Please for the love of god check out the wikipedia article; I didn't include more information from it on here because there's literally too much that's interesting and I'd have to c/p the entire thing.
