How Two Apps and a Battle Index Are Bringing Civil War Ancestors Back to Life

A reader once typed her own last name into a search box on my website. Thirty seconds later she read six words that changed how she saw her family. Her great-great-grandfather earned the Medal of Honor.

That is the kind of moment I built these tools for. I write novels about the Civil War, and somewhere along the way I started building software too. It began with a simple question. Readers of Cadets to Captains kept asking if their own ancestors fought in the battles I described. I could not answer quickly. So I built a way to find out.

Muster Roll: Search a Name, Find a Soldier

The first tool is called Muster Roll. It draws from the National Park Service’s Civil War Soldiers and Sailors System. That public database covers both Union and Confederate service. Type a surname into the search box, and the app returns every soldier who carried that name.

Each result goes further than a bare list. The app resolves the soldier’s unit code into a readable name, like “18th Regiment, Virginia Infantry.” It shows the branch of service, infantry, cavalry, artillery, or one of several others. It shows rank at enlistment and rank at discharge, and flags a promotion when the record shows one. Where a unit fought, the app lists the battles by name and links each one to its full record.

None of that data invents anything. The National Park Service describes its own records as “just an index,” with sparse detail for enlisted men. No birth date. No hometown. I built the app to show readers everything the source holds, and nothing it does not.

The reader I mentioned above is one story among many. She found several ancestors in the database that day, all connected, all real people who marched into real battles. A name on a page is not the same as a name in your own family. When the two meet, something shifts. She now knows exactly which regiment her ancestor served with, and which battles he marched into. She found that in under a minute.

Battles: What Happened, Where, and Why It Mattered

The second app, Battles, works from the opposite direction. Instead of tracing a soldier, it maps a fight.

Search for a battle by name and the app opens a detail page. It shows the date, location, and commanding generals. Troop strength appears where the record allows it, along with a short account of the day. For the battles tied to my novels, readers can see the exact regiments my characters stood beside in the story.

The order of battle is the part that took the longest. Union rosters are well documented. Confederate rosters, especially for smaller engagements, scatter across dozens of sources that do not always agree with each other. I built the Confederate order of battle one engagement at a time. I checked each unit’s participation against multiple accounts. I left a battle blank rather than guess when the sources ran dry.

Ten battles in the database show no Confederate units at all. That is correct, not a gap. No Confederate forces fought in those engagements. The app now says so plainly instead of showing a confusing empty page.

That kind of care is slow work. It is also the only way I know to keep the history honest. A reader checking a battle in the app gets the same answer a historian gets from the Official Records.

The Battle Index: A Simple Way to Browse

The newest piece is smaller than the other two, and it exists for a simple reason. Not every reader wants to search. Some want to browse.

The Battle Index lists all 382 principal battles of the war in order. It runs from Fort Sumter in April 1861 to Palmito Ranch in May 1865. A reader can scroll the whole war on one page, or filter it down to a single state or year. Some battles carried two names, one used by the Union and one by the Confederacy, like Bull Run and Manassas. The index shows both names where they exist, as with Antietam and Sharpsburg. Most battles never carried a second name, and the page says that plainly instead of pretending otherwise.

The index is meant to sit next to the other two tools as a starting point. A reader who does not know what to search for yet can open the index. From there, they can find a battle near their home state and follow the link into the full record.

Try It Yourself

Search your own surname in Muster Roll right now. It takes less than a minute, and you might turn up your own six-word moment, the way that reader did. If a name catches your eye, open Battles and read about the fight your ancestor marched into.

Read the Series

These tools grew out of the Steel and Honor series. The series follows two West Point cadets, one bound for the Union and one for the Confederacy. It traces them from their cadet years into the war that split the country.

Book One, Cadets to Captains: 1848-1860:

Book Two, Antietam: From Secession to the Bloodiest Day, is out now. Full retail links go here once Curtis confirms them. Until then, read the free

Coming soon, Book Three, Gettysburg and Vicksburg: Summer of Decision, the next chapter in the McAllister and Tanner story.

What Should I Build Next?

I keep a running list of what to add. A map view that plots each battle by location sits near the top of that list. So does a way to chain related battles into a single campaign. That would let a reader follow the Overland Campaign or the fall of Vicksburg one fight at a time. No one would lose the thread. Both ideas came from watching how readers already use the tools, not from a plan I set at the start.

If you use Muster Roll or Battles and think of a feature that would help, tell me about it. I read every message. I am always glad to hear a good idea for where to take these tools next.
