Here’s Will Greene at the 2021 Pamplin Park symposium giving a great talk on the First Offensive at Petersburg. Unfortunately, his microphone cut out a few times early in the talk. The technical folks were able to fix it, though.
The video’s description reads, “Former Pamplin Historical Park Executive Director Wilson Green talked about Civil War Petersburg, Virginia. He focused on Union General Ulysses Grant’s first offensive against the earthworks protecting Petersburg in June 1864. This program was part of the annual Pamplin Historical Park Civil War Symposium.”
