After the end of the Republican offensive, the Republican army of the Ebro was trapped in a pocket with its back to a river and Nationalist officers wanted to attack across the unprotected Segre River and advance to Barcelona, but Franco wanted to destroy the Republican Army of the Ebro and to recover the lost territory. The Nationalists concentrated most of their artillery and air forces in the Ebro's Front. On the other hand, the Republican high command ordered their troops to resist and not to retreat. Officers and men were executed for retreating.
