During the Spanish Civil War the Falange, which was since its inception quite military or paramilitary, like other equivalent youth parties in countries under totalitarian regimes, became an important part of the National Army (or National Movement), both ideologically and militarily, still as an independent organization but strengthening the regular insurgent army in the combat lines, which caused plenty of Falangist casualties, and "Cara al sol" was their anthem throughout "the war days", the lyrics acquiring an even more special signification for its remembering of the "fallen comrades".
