Spanish Civil War Chronology 1937

13th December 1936 - 15th January 1937

THE BATTLE FOR THE CORUNNA ROAD

As the frontal attack upon Madrid had failed, the Nationalists now tried to tighten the siege and to cut off the capital from the rest of Republican Spain. On 13th December General Jose Varela launched an offensive towards the Corunna Road, which runs 25 miles to the North of Madrid. Between 3rd and 15th January his forces held a 7 mile stretch of the road against fierce attacks by Republican troops but, as casualties mounted on both sides, it became apparent that the situation had become a stalemate.

17th January - 6th February 1937

THE BATTLE FOR MALAGA

With the arrival in Spain of the Italian "volunteers" the Nationalists now felt able to mount an offensive on the southern provinces of Republican Spain. Three Nationalist columns converged on Malaga; the Army of the South, led by General Gonzalo Quiepo de Llano, advanced from the West; from Granada, to the north-east of the city, came forces under the command of Colonel Antonio Munoz; and moving down from the North were the Italians, led by General Mario Roatta. Although large numbers of Republican troops were available to defend Malaga, they were badly organised and they steadily retreated. By 3rd February the attackers had reached the outskirts of the city and, three days later, when the last defenders fled northward towards Almeria, the Nationalists entered Malaga.

6th - 24th February 1937

THE BATTLE OF JARAMA

The Nationalists renewed their attempts to capture Madrid. This time they concentrated their efforts upon cutting the Valencia Road where it runs through the Jarama Valley to the south-east of the city. The Nationalists, under the leadership of General Luis Orgaz, began their assault on 6th February and, by 11th February, they had driven the Republican army, commanded by General Sebastian Pozas, eastwards across the River Jarama. To restore the situation General Jose Miaja took over personal command of the dispirited Republican troops on 15th February. By 24th February, when the fighting finally ended, the Nationalists had driven a salient into the Republican front-line but had failed again to cut Madrid off from the rest of the Republic.

8th - 18th March 1937

THE BATTLE OF GUADALAJARA

The Nationalist forces threatening Madrid were ordered to attack around the north-east of the city in an attempt to cut it off from the rest of the Republic. Two Nationalist armies advanced towards Guadalajara, which is 34 miles from Madrid, and pushed back the inexperienced Republican troops that faced them. The right-hand (or western) army, which was commanded by General Jose Moscardo, had little trouble in forcing the opposing Republican troops back, but the left-hand (or eastern) army, which was composed of Italian "volunteers" and led by General Mario Roatta, experienced stiffening resistance after their capture of Brihuega on 10th March. General Roatta halted his advance on 15th March to re-group and the Republicans used this break in the battle to mount a counter-attack. Two divisions, assisted by Soviet tanks and aircraft and led by Colonel Enrique Jurado, fell on the leading Italian units on 18th March. The ferocity of the counter-attack surprised the Italians and their retreat rapidly became a rout. Moscardo's army was forced to fall back because of the Italian collapse and the Republic recaptured Brihuega. Although the Nationalist attack had gained some ground when the battle finally ended, it had failed to achieve the decisive result that had been hoped for.

31st March - 19th June 1937

THE BATTLE FOR BILBAO

The Nationalists forces in the North, led by General Emilio Mola, began an offensive against Basque forces in Vizcaya with the intention of capturing the Basque stronghold of Bilbao. The Basques, who were not well armed and who were led by General Francisco Llano de la Encomienda, gave ground, and the towns of Durango and Guernica surrendered on 28th April after suffering heavy bombing by units of the German Condor Legion. After the death of General Mola in an air crash on 3rd June, General Fidel Davila took command of the Nationalist forces. By 11th June the Basques had withdrawn behind the "Ring of Iron" defences around Bilbao, but these proved to be less than effective when subjected to heavy artillery bombardment. Under cover of the bombardment the Nationalists breached the outer defences and the "Ring of Iron" collapsed. On the night of 13th June most of the civilian inhabitants of Bilbao were evacuated, and on 18th June the last units of the Basque army, now led by General Mariano Gamir Ulibarri, abandoned the city. The Nationalists entered Bilbao on the next day.

19th April 1937 The Falange and Carlists Movement were united and became the FET (Falange Espanola Tradicionalista y de las Junta de Ofensiva Nacional-Sindicalista).
23rd April 1937 The Madrid Defence Junta was dissolved.
30th April 1937 During the blockade of Bilbao, the Nationalist battleship Espana hit a mine and sank off Cape Penas near Santander.
3rd - 8th May 1937 Street-fighting broke out in Barcelona; the CNT (Confederacion Nacional de Trabajo [the Anarcho-Syndicalist Trades Union]) and POUM battled with the Communists supported by the Generalitat.
7th May 1937 The Nationalist motor torpedo boat Javier Quiroga sank off Gibraltar.
15th May 1937 Largo Caballero resigned as Prime Minister.
17th May 1937 After the resignation of Largo Caballero, Dr Juan Negrin (a Socialist) became Prime Minister. The new Government was dominated by Communists.
31st May 1937 The Republicans began an offensive to capture Segovia. Three Republican Divisions, under the command of General Domingo Moriones, broke through the Nationalist front-line at San Ildefonso and captured La Granja. Nationalist troops, led by General Jose Varela, were detached from the Madrid front and used to mount a counter-attack that stopped any further Republican advance.
16th June 1937 The POUM was outlawed and its leaders were arrested.
17th June 1937 The Republican battleship Jaime I blew up and sank at Cartagena.
18th June 1937 The Nationalist motor torpedo boat Falange sank.
21st June 1937 Andres Nin (leader of the POUM) was murdered by Soviet agents.
6th - 26th July 1937

THE BATTLE OF BRUNETE

After the failure of the Nationalist attack upon Guadalajara the Republican troops around Madrid went on to the offensive. General Jose Miaja ordered two Republican Corps (led by Generals Juan Modesto and Enrique Jurado) to advance southwards from the El Escorial - Madrid road towards Brunete. This would then cut off the Nationalist forces besieging Madrid from the West. Their initial thrust captured Brunete and drove a 5 mile salient into the Nationalist front-line. The Nationalist armies, under the command of General Jose Varela, then rallied and mounted a counter-attack that forced the Republicans almost all the way back to their start line.

10th August 1937 The Council of Aragon was dissolved by the Republican government.
14th - 25th August 1937

THE BATTLE FOR SANTANDER

After capturing Bilbao, the Nationalist forces in the North of Spain switched their offensive towards Santander. The Nationalists, who were led by General Fidel Davila, advanced westwards through the Cantabrian Mountains. Despite the large numbers of troops General Mariano Gamir had under his command, Republican resistance was weak. This weakness was due, in the main, to poor training and a shortage of weapons. On 23rd August the Basque forces in the Republican army surrendered to General Ettore Bastico, and because further resistance was impossible, Ulibarri abandoned his remaining troops and flew to safety in France. The Nationalists were then able to enter Santander almost unopposed.

15th August 1937 A new political police force, the SIM (Servicio Investigacion Militar), was formed in Republican Spain. It was controlled by the Communists and contained many Soviet "advisers"
24th August - 30th September 1937

THE BATTLE FOR SARAGOSSA

The Republican Army of the East, led by General Sebastian Pozas, advanced into Aragon from Catalonia to capture Saragossa. They pushed back the Nationalist forces (which were commanded by General Miguel Ponte) to the North and South of the River Ebro, but were unable to dislodge them from the area around Saragossa or to capture Huesca (in the North) or Teruel (in the South). By the end of September the offensive had ceased to have any impetus and had come to a halt.

1st September - 21st October 1937

THE BATTLE FOR GIJON

After the capture of Bilbao and Santander the only remaining Republican stronghold in the North was Gijon and the surrounding area. The Nationalists, who were led by Generals Antonio Aranda and Jose Solchaga, launched an offensive through the Mountains of Leon and along the coast from the East to capture Gijon. Aranda's forces were unable to break through the mountain passes, which were defended by Asturian troops, until a Navarrese force, under Solchaga's command, captured the village of Infiesto. This out-flanked the defences and the Asturians were forced to retreat. On 21st October Gijon surrendered and the whole northern coast of Spain now passed into Nationalist control.

1st October 1937 Largo Caballero was removed from the leadership of the UGT (Union General de Trabajadores [Socialist Trades Union]).
20th October 1937 The Republican submarine C6 was scuttled at Gijon after suffering damage during a Nationalist air attack.
21st October 1937 The Republican destroyer Ciscar was sunk at Gijon by Nationalist aircraft.
31st November 1937 The Republican Government moved from Valencia to Barcelona.
15th December 1937 - 20th February 1938

THE BATTLE OF TERUEL

The Republican Army launched an offensive to capture Teruel to pre-empt a Nationalist attack upon Catalonia. Two Republican armies (led by Generals Hernandez Sarabia and Leopoldo Menendez) advanced on Teruel and by nightfall on 15th December they had surrounded the city. The garrison, which was commanded by Colonel Rey d'Harcourt, held out in the southern part of the city until 8th January; casualties and lack of supplies then forced them to surrender. On 29th December General Franco had ordered Generals Jose Varela and Antonio Aranda to mount a counter-attack to relieve the defenders but the appalling winter weather hampered their advance and d'Harcourt had surrendered before they could raise the siege. The Republicans now found that they were in danger of being besieged in Teruel themselves. On 7th February Nationalist cavalry attacked the Republican forces to the North of the city and forced them to retreat and by 17th February Moroccan troops (led by General Juan Yague) had crossed the River Alfambra. Three days later the Nationalists had almost surrounded the city and the Republican armies were forced to retreat along the Valencia road to the south-east. The Nationalists then reoccupied Teruel.
