No offense, but I wouldn't put the Alamo on there. Since I majored in history, I read that US citizens kept coming over to Texas and pretty soon thought Texas was part of the US so they defended it even though it was still part of Mexico. The Mexican government did grant US citizens to come to Texas to live only if they would become Mexican citizens. The people did say yes, but they still acted like US citizens and never adopted the mexican customs.
The Alamo doesn't actually show freedom for the US since they were fighting for a land that was never theirs in the first place. Just thought I'd give an opinion.
