Maybe I misread Stewart, but (like
Phil_Draper said up-thread) I belive the brokies in the OP example =can= use Low Crawl to avoid immediate surrender.
Here again is the OP graphic:
View attachment 21320
Among the
All other Rout provisions is the option of
using Low Crawl so as to limit the Rout to one hex.*
*[Surrender troubles aside, there are instances in play when a Low Crawl may be preferable to a "normal rout" merely to keep a brokie "near the front." Trading a more difficult future Rally DR for a better Good Order position should the brokie make that more-difficult Rally DR is a risk sometimes worth considering in game play.]
The omniscient player knows that no Known unit can Interdict I9, meaning
Surrender to the K9 unit isn't required (IMO).
The omniscient player must designate a Rout Target of H8 or H9 (consequence of A10.51)
but knows too that a normal Rout to H8 or H9 and actually getting there will result in Surrender to a G9 or G10 unit.
A10.52 allows and kinda focuses on Low Crawl as a means of avoiding Interdiction
but also allows Low Crawl =period=, provided
All other Rout provisions are met.
Re the player seeking to dodge Surrender in this example, designating the Rout target determines the Rout direction, but the rules do not compel a "normal rout" if there is an allowable Low Crawl option and (in this case) there is, IMO.
Re the OP example, I'm believing rules I've cited in this post =do= allow a Low Crawl to I9, say, but
when not all of our several Mavens are in accord, then
Yes, a Q&A could show that my belief is wrong.
Maybe someone disagreeing w/my belief will make the submission (if still believing I've misread the rules).
