Getting Your Hands on The Memoirs Of Henry Heth
Henry Heth was the Confederate brigadier general who sent his troops into what became the opening engagement at Gettysburg on July 1, 1863. His memoirs were published in 1903, edited by his son James H. Heth. You can find a scanned copy on the Internet Archive, and there are also cheap print-on-demand editions floating around on Amazon that are basically the same thing. The original text is out of copyright. That means there are several digital versions running around. The most complete one I use is the HathiTrust digitization of the 1903 Pennsylvania History publication. It's searchable, which matters when you're looking for a specific passage about wagon trains or command decisions on that morning. The Internet Archive version has some OCR errors on the map plates, but the prose itself reads fine. There's also a free version on Project Gutenberg. I checked it against the HathiTrust text a while back and it matches closely enough, though it lacks some of the editorial notes in the margins of the original. If you're doing serious citation work, go with HathiTrust or the original book scan. Don't bother with the Gutenberg edition unless you just want to read through it quickly.
What the memoirs actually contain
The book runs about 350 pages. It covers his early career, the Mexican-American War service, prewar postings, and then the bulk of it is the Civil War, with heavy focus on Gettysburg and the later campaigns. Heth writes in a fairly dry, matter-of-fact style. He doesn't spend a lot of time self-justifying, which is unusual for Confederate generals from that era. Most of them write memoirs that read like legal defenses. Heth's reads more like someone describing what happened and moving on. The section on Gettysburg is the one everyone reads. He describes sending Anderson's and Davis's brigades forward on the morning of July 1st, not knowing there was a significant Union force in front of them. His account of riding into the Union picket line and realizing too late what he'd walked into is one of those moments that gets repeated in every Gettysburg book ever written.
Using the memoirs for actual research
Here's the thing most people miss. Heth wrote this in 1902, nearly forty years after the war. Memory fades. Names get confused. Dates shift. I spent a weekend cross-referencing his account of the 1st Maryland Confederate's position on the morning of July 1st with the official records and several unit diaries, and his timeline was off by roughly two hours on the initial movements. Not catastrophically wrong, but enough that if you're building a minute-by-minute reconstruction, you need to verify everything against primary sources. His descriptions of troop positions tend to be directionally correct rather than precise. He'll say "moved toward Seminary Ridge" and that's useful for understanding his general intent, but if you need to know exactly where a specific regiment was at 6:30 AM, his memoirs won't give it to you. Go to the Official Records instead. Use Heth to understand what he was thinking, not where his men precisely stood at any given moment. Another practical issue I ran into. The 1903 edition has footnotes and editorial additions by James Heth that are mixed into the text without clear visual separation in most digital copies. In the HathiTrust version you can tell because they're in smaller type and sometimes italicized, but in plain text downloads they just blend together. I've seen people cite editorial commentary as if it were Henry Heth's own words. Make sure you know which is which before you reference anything.

What the memoirs don't cover well
Heth barely mentions J.E.B. Stuart or the cavalry situation at Gettysburg. He had complaints about the cavalry coverage and the lack of reconnaissance, but he's vague about it. If you're researching the cavalry picture, you'll need to go to other sources. The memoirs also don't give you much on the command friction between Heth andhis superior William Dorsey Pender, which is interesting considering Pender was his direct brigade commander at Gettysburg and they had a documented disagreement about the morning assault. There's also very little about the experience of the common soldier. Heth writes about formations, movements, and command decisions. He mentions casualties in aggregate numbers but doesn't describe individual actions or the ground-level experience. If that's what you're looking for, you'll want unit diaries and letters instead. The memoirs are a commander's view, not a soldier's view.
A few technical notes on reading it
The original has a few maps that are useful if you can read them. The digital versions sometimes render them poorly, especially the color plates. I keep a high-resolution scan of the Gettysburg map plate open while I read the relevant chapters. Without it, you're trying to visualize troop movements based entirely on textual descriptions, which gets confusing fast. The book is dense with names. Hundreds of officers mentioned with only brief identifications. I keep a quick-reference sheet of the key brigade and regiment commanders open while reading. Once you've read it through once, you start recognizing the patterns, but the first pass is rough without help. If you want a single-volume companion that annotates Heth's account and flags the discrepancies, I found Heth's Division at Gettysburg by William C. Davis helpful. It's older and out of print, but library copies exist. It doesn't replace the memoirs, but it does point out where Heth's recollection diverges from the documentary record, which saves you the work of figuring it out yourself.
