I'd like to ask you guys what the rules are for shattering armies - meaning armies dying completely the moment combat begins. I encountered it before, but since now I always thought it happened when the dying army was SO extremely weak compared to the surviving one that there was some sort of instant defeat - rule.
However, today I lost a fresh regiment of 1000 irishmen, happily besieging an English fortress in Glamorgan, to a bunch of RETREATING (i.e. weakened in their moral department) English. It was two armies of English, army 1 consisting of two infantry and one cavalry regiment (survivors of battle before: 233/480/0) and army 2 consisting of a single infantry regiment (survivors 0/454/0). Neither me nor them had a general. Arrival date was the 30th, so no last minute reinforcements on the English side. Admittedly they had longbows, while I still had medieval infantry. I'm playing no mods, Heir to the Throne, no new updates available via the launcher, the readme file giving me a "changes for 3.2.", so I guess I have a 3.2 patch for HTTT. Any help appreciated!
