Yes, the host is able to generate log files for all the battles that happen in a turn, and the players can see the same debug info if they look at the battle report with debugging turned on. But you can't watch battles as a player that you don't have battle reports for.

In SP gaming, since you're the host, you can see the battles happening in the log files, but that's not really very useful to understand what happened. The proposed Watcher nation mod which nobody so far bothered to complete would allow to see them. Or if you can, just cast the "Eyes of God" global.

The Debug Console thing that I wrote about is a developer tool built into Dom3. It features a basic battle simulator, which isn't terribly useful, just for testing out abilities and weapons on multiple units.
