Over the course of the summer of 1937, the new army launched various offensives on the Aragon Front, with the primary objective of distracting enemy troops who had been attacking the Republican forces in Madrid and the Northern Front. In June, the unit launched the offensive for Huesca, which ended in failure. At the end of August it started an offensive of even greater calibre, this time directed against Zaragoza, which also ended in failure, although the main focus of Republican operations at the time was in Belchite. Following these failures, two new offensives were launched in Autumn: one more attempt against Zaragoza, and the Biescas Offensive, in the Huescan comarca of Alto Gállego.
