Online Source for Roman Republican Wars

[Bryan]

I am trying to find an online source of the wars Rome fought in from the 2nd Punic War to Caesar's Civil War. Does anyone know where I can look? I've tried Wikipedia but it isn't accurate. A Google search didn't help much either.

I'd appreciate whatever help you can give.

For me, Polybius should be your first read. However, you should clarify whether you are interested in modern or ancient sources.
