According to Beevor, the defense of the XYZ Line was a far greater victory for the Republic than the Battle of Guadalajara. The Nationalists occupied the province of Castellon, but failed to occupy Valencia and suffered heavy casualties. The Republican Army had time to reorganize, and to plan the assault across the River Ebro. Furthermore, the Republican forces in Catalonia had time to rearm with the weapons received across the French frontier, reopened in March.
