Short question on Routing and Timing

[tinkthank]

When do routed troops show up?

Assume provinces A, B and C are neighbors. A and B are friendly neighbors owned by me, C is an enemy neighbor.

Let's say that in province A, I have 5 commanders and 50 troops. In Turn X, Province A gets hit by the Ghost Riders spell. Furthermore, a conventional army has moved in from C to attack me on turn X.

Let's say I repel the Ghost Riders spell, but 10 of my troops have routed.
Let's say too that I have lost the battle in A, but that 3 of my commanders and a further 10 of my have survived to rout. All of the survivors from both attacks have routed to province B.

Now will those routed troops first show up in turn X+1 or in turn X? If they show up first in turn X+1, when will they do so?
In other words:
1. Will those routed troops (which ones? the ones from the ghost riders spell? all? none?) fight any battles on turn X if province B if province B was also the target of a conventional battle? Of a magical battle if it happened after the first one on turn X?
2. Will those routed troops fight against magical battles in turn X+1? Conventional battles?

Thank you.
