I placed this under Army Red tape since its a better fit here.

The Federals began the war with a Regular Army organized into an essentially Napoleonic, musket-equipped structure. Each of the ten prewar infantry regiments consisted of ten 87-man companies with a maximum authorized strength of 878. At the beginning of the war, the Federals added nine Regular infantry regiments with a newer "French Model?" organizational structure. The new regiments contained three battalions, with a maximum authorized strength of 2,452. The new Regular battalion, with eight 100-man companies, was, in effect, equivalent to the prewar regiment.  

Here comes my questions.
Was the company lettered A thru H for each Battalion of the Regiment?
Example: 1st Battalion, 11th Infantry Regiment Company A thru H.
2nd Battalion, 11th Infantry Regiment Company A thru H.

The more I think about it I believe this to be the case since I have never heard or come a crossed a Company P.  

Also did each Battalion have their own Colors?

Thanks,

The answer to your first question is yes, each battalion had (in theory at least) companies A-H. As for the colors, I recall reading that each battalion had nationals, but don't quote me on that one...
