The next HISTORYtalk will be with Bob O’Neill on September 15 at 7 p.m. EST via Zoom. His talk will be: Cavalry on the Road to Gettysburg: Aldie, Middleburg, and Uppervill Re-examined. Following the talk will be a Q&A period led by Eric Wittenberg.

Talk Synopsis

Contrary to popular belief, Maj. Gen. Joseph Hooker, commanding the Army of the Potomac, neither ordered nor desired his cavalry to search for Robert E. Lee’s Army of Northern Virginia in mid-June 1863. Bob O’Neill will explain what Hooker asked his cavalry to do and how, by disobeying his orders, cavalry commander Alfred Pleasonton precipitated a series of clashes with Jeb Stuart in Northern Virginia’s Loudoun Valley.


Bob O’Neill is the author of two books and numerous magazine articles. A retired police officer, his newest book, Small but Important Riots, Aldie, Middleburg, and Upperville will be published in 2022. Learn more about the Union cavalry and the clashes in the Loudoun Valley on Bob’s website at
