After every boss clear you will be prompted if you want to return. If you select yes, lost troops will stay lost and sustained damage will remain, but you can change things back at the keep without losing action counter. If you choose to retreat at any other point, you lose any remaining moves on your dice roll, and when resuming you pick back up from the last returnng node, ie boss you defeated.

To my experience if you have 2 moves left after a tough boss fight, it's ideal since it lets you backtrack to the pre-boss node for an easy fight, then heal back to full/restore lost troops at the once-boss-now-recovering point. It's also the checkpoint, so you can pull back without losing dice moves (not counting the two moves used for healing, but for a free heal on lv70+ swords who would otherwise take half a day to repair, it can seem fair). I backtrack for full heal every time befor entering the citadel, personally.
