Can some arriving elements move away from their landing points to make room for more arriving elements in the same bound? Or do the arriving troops have to arrive one rank deep across the whole command?
Also, enemy elements have to make room for arriving impressed shipping troops. Seeing as doing so means they're well within the 400 pace limit for arrival surprise, is the resulting flee move in addition to the making room move?
(Just canvassing possible tactics...)
According to the
Arrival by impressed shipping section on page 31, only foot can move and as single elements. It is not clear whether all elements have to be placed before any move. However, that may not be an issue because it also says they are placed with their
rear edge on a beach or quay. As a beach can be up to 120p wide (p20), this allows you to place multiple ranks if you model the terrain with a wide beach.
Arrival surprise fleeing only applies to land elements surpised by
land flank marches, or to naval fleeing from naval elements that would contact them. Enemy do not flee from troops delivered by impressed shipping.
