The Baton Rouge was the capital of the U.S. state of Louisiana and later a Protection Camp. By 1953, Baton Rouge became the last stronghold for American forces after the Liberty Defense Perimeter was breached by the Chimera. It held at least 3 million surviving refugees.
The destruction of the LDP and the fall of most of the American mainland resulted in Baton Rouge not receiving supplies from SRPA for many weeks. Baton Rouge apparently held out well, but according to Joseph Capelli, it can be presumed that if SRPA failed in stopping Daedalus, Baton Rouge would fall.
