I presume Barry the last photo was a chap dressed as an early member of the Marine Corps. I assume the men in this fine photo of an historical picture are members of the Marine Corps of a later period. If not forgive my ignorance. I have searched a little on the internet and you've got me here. Looks like they are breaking a seige of some kind.I dont know what it relates to. It is a mighty fine photo. I now know the Corps Latin moto means in English 'Always Faithful'. Fine Photography!
