Spanish Civil War
Nationalists launched the Aragon Offensive
On 7 March, Nationalists launched the Aragon Offensive, and by 14 April they had pushed through to the Mediterranean, cutting the Republican-held portion of Spain in two. The Republican government attempted to sue for peace in May, but Franco demanded unconditional surrender, and the war raged on. In July, the Nationalist army pressed southward from Teruel and south along the coast toward the capital of the Republic at Valencia, but was halted in heavy fighting along the XYZ Line, a system of fortifications defending Valencia.
