I personally love this type of drama. So feel free to send me the posts and screen caps. I eat that stuff up.
Regardless, poaching is part and parcel how regiments go. Happens all the time.
Usually though, you get lucky and the people that leave your regiment were all the nimrods who would have wound up destroying your regiment in one way or another regardless of what happened.
The most brutal of all successions is when an officer, working behind the scenes, waits for the most opportune time (Usually when the regiment leader is on vacation, or taking time off for a family members funeral, etc) and absconds with a 2/3rds of your regiment. How you react after this happens (60% of the time to most regiments) will follow you for all time! Or at least for about two weeks.
Then everyone just lives life like nothing happened.
