Eastern Army (Spain)

After the breakout of the 1936 civil war in Spain, the Catalan government looked to create its own army, independent of the organic structures of the Republican army which operated in the rest of the Republican territory. On 6 December 1936, the Catalan Ministry of Defence declared the creation of the People's Army of Catalonia.{{Cite book|last=Ucelay da Cal, Enric, 1948- Gonzàlez i Vilalta, Arnau.|title=Contra Companys, 1936 : la frustración nacionalista ante la revolución|date=2012|publisher=Universidad de Valencia|oclc=1001427232|language=es}} However, this army existed far more on paper than it did in reality, as the anarchist militias continued to have a great degree of autonomy, and in many cases did not become part of the new army. After the May Days battles in Barcelona, the Republican government recovered its competencies in the area of defence, and General Sebastián Pozas assumed command of military forces in Catalonia.{{Cite book|last=Thomas|first=Hugh|title=La Guerra Civil española|others=Daurella, Neri|year=1976|isbn=978-84-663-4469-2|location=Barcelona|language=es|oclc=1057791440}} The army of Catalonia was dissolved, and its units were integrated into the main Republican army.{{Cite book|last=Pagès|first=Pelai|title=War and revolution in Catalonia, 1936-1939|date=10 October 2013|isbn=978-90-04-25427-5|location=Leiden|oclc=861199745}} These units formed the newly-created Ejército del Este, which went on to man the Aragon front.{{Cite book|last=Gabriel|first=Pere|title=Historia de la UGT.|publisher=Siglo XXI de España Editores|others=Castillo, Santiago|year=2011|isbn=978-84-323-1195-6|edition=1st|location=Madrid|oclc=233814612}} The previous militias were forcefully conscripted into the Republican army.

The decree that created the Eastern Army also establishes three new army corps — the 10th, 11th and 12th — into which the militias were integrated.{{Cite book|last=Maldonado|first=José María|title=El frente de Aragón : la Guerra Civil en Aragón (1936-1938)|publisher=Mira Editores|year=2007|isbn=978-84-8465-237-3|location=Zaragoza|pages=171|oclc=232536997|language=es}} The colonel Vicente Guarner Vivancos was named the Chief of Staff of the Eastern Army.{{Cite book|last=Alpert, Michael, 1936-|title=El ejército republicano en la guerra civil|date=1989|publisher=Siglo Veintiuno Editores|isbn=84-323-0682-7|edition=2nd|location=Cerro del Agua, Mexico D.F.|oclc=22427647|language=es}}

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,{{Cite book|last=Thomas|first=Hugh|title=La guerra civil española|url=https://archive.org/details/laguerracivilesp0000thom|url-access=registration|publisher=Grijalbo Mondadori|year=1995|isbn=84-253-2767-9|location=Barcelona|pages=[https://archive.org/details/laguerracivilesp0000thom/page/742 742]|oclc=35285188|language=es}} which ended in failure. At the end of August it started an offensive of even greater calibre, this time directed against Zaragoza,{{Cite book|last=Thomas|first=Hugh|title=La guerra civil española|url=https://archive.org/details/laguerracivilesp0000thom|url-access=registration|publisher=Grijalbo Mondadori|year=1995|isbn=84-253-2767-9|location=Barcelona|pages=[https://archive.org/details/laguerracivilesp0000thom/page/780 780]–781|oclc=35285188|language=es}} 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.{{Cite book|last=Flores Pintado|first=Miguel|title=Guerra Civil, Aragón|last2=Gascón Ricao|first2=Antonio|last3=Martínez De Baños Carrillo|first3=Fernando|publisher=Delsan Libros|year=2005|isbn=84-95487-35-7|edition=3rd|location=Cuarte de Huerva, Zaragoza|language=es|oclc=57690522}}

In March 1938 Franco's army launched a strong offensive against the republican lines on the Aragon Front. In just a few weeks the Eastern Army was practically destroyed by the attacking "nacionales",{{Cite book|last=Thomas|first=Hugh|title=La guerra civil española|url=https://archive.org/details/laguerracivilesp0000thom|url-access=registration|publisher=Grijalbo Mondadori|year=1995|isbn=84-253-2767-9|location=Barcelona|pages=[https://archive.org/details/laguerracivilesp0000thom/page/858 858]|language=es|oclc=35285188}} additionally losing a great amount of territory. As a consequence, General Pozas was removed from his post, and in his place the colonel Juan Perea Capulino was installed.{{Cite book|last=Alpert|first=Michael|title=El ejército republicano en la guerra civil|publisher=Siglo Veintiuno Editores|year=1989|isbn=84-323-0682-7|edition=2nd|location=Cerro del Agua, Mexico D.F.|language=es|oclc=22427647}}{{rp|346}}

During April 1938, the Segre River became the new defensive line for the Eastern Army. In May, the unit participated in the Balaguer Offensive, which among various objectives looked to test the capacity of the new forces that the unit had.{{Cite book|last=Salas Larrazábal|first=Ramón|title=Historia del ejército popular de la República|publisher=Esfera de los Libros|year=2006|isbn=84-9734-465-0|location=Madrid|pages=1851|language=es|oclc=69675818}} However, the offensive did not end in the success that was hoped for,{{Cite book|last=Salrach i Marés|first=Josep|title=Diccionari d'història de Catalunya|last2=Mestre i Campi|first2=Jesús|last3=Termes|first3=Josep|publisher=Edicions 62|year=1992|isbn=84-297-3521-6|location=Barcelona|language=ca|oclc=27528441}} so the unit recentred itself around its defensive duties.

Towards the end of 1938, during the first few days of the Catalonia Offensive, the Eastern Army maintained a bitter resistance against the advancing enemy. However, after suffering great losses, the forces began moving towards the North. The Eastern Army was later dissolved when, at the start of February 1939, its units crossed the French border.{{Cite journal|last=González|first=Antonio Santos|date=2016|title=24ª Brigada mixta del Ejército Popular de la República II: milicianos de Sierra Mágina en las batallas del Ebro, Cataluña y su huida a Francia|url=https://dialnet.unirioja.es/servlet/articulo?codigo=6874791|journal=Sumuntán: Anuario de Estudios Sobre Sierra Mágina|language=es|issue=34|pages=115–164|issn=1132-6956}}
