meaning - (of which) Seventy (of which) are from the northern region

I have a question about the meaning of two different sentences:

1. The battalion consists of two hundred soldiers, seventy of which are from the northern region, stationed along the coast.


2. The battalion consists of two hundred soldiers, of which seventy are from the northern region, stationed along the coast.

In sentences 1 & 2, does "stationed along the coast" apply to all two hundred soldiers of the battalion, or just the seventy soldiers from the northern region?
