Maybe some of you Texans can help me here. I'd like to be pointed towards a historical reference discussing the nitty-gritty details of the admission of Texas to the Union. I'm not interested in culture, parties, speeches, etc., but rather the legislative steps towards admission. For example, I have heard that Texas was offered admission to the Union in an act of Congress permitting Texas to enter as from 1 to 5 states, but that Texas decided to come in as a single large state (forfeiting up to 8 Senators!). Why was this decision taken? I'm also interested in a discussion about what was different about the admission of Texas, since it entered the Union as an independent country as opposed to a former territory of the US.
