So since you mentioned it, I'll give you a teaser:
My book (which, knock on wood) is currently with a publisher for review right now, is on the 1812-13 revolution in Texas. It's commonly called the Gutierrez-Magee Expedition, or you might have simply heard of the Battle of Medina. All that's selling it short, because it's a revolution in the full sense, as detailed, nuanced and even dramatic as the 1836 revolution. I've captured a lot of that in my book.
The biggest insight I've had is on the origin of the filibuster into Texas. It's always been presented as, well these guys just showed up and invaded Texas, but it's far deeper than that. What I found is that the fundamental elements of the filibuster were in place or moving towards Texas before either Augustus Magee or Bernardo Gutierrez de Lara arrived on the frontier. They simply inherited a filibuster in embryo and were appointed at its head because it needed 1. A real live Mexican rebel to give it legitimacy (Gutierrez) and 2. a military commander to give it order (Magee).
There were basically 2-3 groups that built up the filibuster, and the focus of my presentation is on one of them. It is an obscure smuggling ring that the Spanish broke up, and which ultimately led to the development of the infamous neutral Ground banditti who raided Spanish commerce.
There's a lot of stuff here that I found as part of my thesis and subsequent research that no one ever did. I read through about 1200 pages of the Bexar Archives and have keyword searchable access to tens of thousands more. I dug through the US National archives and other sources. I found little confirming bits in even the smallest details. There is a smuggler named Quirk who plays a key role, and then there is a secret spy sneaking into Texas to connect Tejano rebels with American filibusters who is named Quist. Most historians have simply taken this on fact and not delved into it. I saw those two names and thought, wait a minute. So I tracked down the source of "Quist" and it's a grainy cursive letter in the National Archives. I found the original author of that letter's copy, and its clearly "Quirk." I also identified the mysterious "Smith" who is offering to bring American rebels to aid the Mexicans. He is fascinating and has a great history.
The rest of the origin story is the insight that I had after digging deeper than anyone else, that the fact that Aaron Burr wanted to invade Texas in 1806 and that someone actually invaded Texas in 1812 are not coincidences. I basically confirmed (although its a giant pile of circumstantial evidence) that this was the case. In the full book, I go into this in a lot more detail. I spent 5 years on this, and it's gone through 6 drafts. It's good, but of course, even then has to go through the vetting process of an academic publisher who is looking at it now.
