Page 30 clarifies what, and by whom, Spontaneous moves are. This section is the main offender-
'Such troops are impetuous on land until broken or the cause ceases;
and until then will advance, automatically renew combat or chase
broken enemy unless controlled. They are:
. Any troops (except train) that are aware of broken or shattered
enemy closer than 400p, or aware of an enemy feigned flight closer
than 400p and have not been halted, or would contact enemy Baggage'
'Impetuous troops must make a spontaneous advance as either
individual
elements or a column unless:
. Their C-in-C or command's generals/was inert, or is an uncommitted
unreliable ally'
