I am currently playing GC with Germany in early 1945. Sometimes my units retreat 4-5 hexes after a breakthrough nearby. What is the mechanic at play here? TOEs and MPs are fine and there is no evidence of fighting. Is it some sort of AI commander trigger when he thinks the line is lost (I have pretty thin defences when this happens) and you are about to be encircled?
This is probably something obvious, thanks!
edit: adding rough pictures what happens, basically allied armour drived through and started trying to encircle Saarbruecken with no real fights. Are the HQs running and units are following suit? (yeah, checked, they got attacked and this is probably the reason? Makes sense).
