It is smaller in size but should still be among top-25 size-wise, I believe.
I think Americans use Alamo as an excuse of cutting Texas out of Mexico. Theri logic is (1)Whites moved there then (2)they should be able to make that land independent of Mexico goverment, which the land belonged to. The "lose" of Alamo and death of civilians preluded the US armed force "invasion". Haha.
