Hi Community!

Once one of my units has been routed, when can I place it back up?

Rulebook, Page 16:

4. Clean Up

All remaining Support and Defense Orders are now removed
from the game board and all routed units are stood to their
upright position

Yes....thanks I just saw it....my bad.

And also keep in mind that even if the enemy invades your territory, which contains only routed units - it will start a normal combat (just the combat power of routed units will equal 0), and only in case if the fight is lost again - those routed units die.

And remember, routed units that are being marched on can receive support as well, and you also play a House Card, just like normal combat.
