"Forget the ___: The Rise and Fall of an American Myth" (5)
I believe the answer is:
alamo
(Other definitions for alamo that I've seen before include "Texas fort famed for defence against Mexican army" , "Texas mission taken by Mexican forces in 1836" , "1836 massacre at a San Antonio, Texas mission" , "Famous Texan fortress" , "ill-fated mission" .)
