Did the coldstream guards form the royal marines?
As far as i am aware there were no Royal Marines on board ships
or protecting civilians, forts,routes, shipping lanes & cargo
from the UK to America, India etc during 18th & 19th
Centuries.
However there is substantial proof & evidence that regiments
of the Coldstream Guards from the Brigade of Guards were
undertaking all the duties as stated above well beyond the 19th
Century, until the Royal Marines were formed.
Needless to say the Royal Marines would never admit to being
formed from the Coldstream Guards.
