August 23

Navarrese forces fighting for the Nationalists claim Mazcuerras Valley and take Mount Ibio, which all-but cuts off the main road and the rail line between Santander and Asturias. Italian forces take Puente Viesgo after facing little Republican resistance.

August 24

Republican General Gámir-Ulibarri orders the general evacuation towards Asturias. Basque fighters begin their withdrawal from the front as the Nationalists are overwhelming the Cantabrian region.

The Republicans begin a major ongoing campaign in Zaragoza, which is their main aim for recapture. Both Belchite and Quinto are heavily guarded town where fighting begins, though Belchite has around 7,000 Nationalists fortified in the the village.

August 26

Santander falls to the Nationalists at last thanks to huge troops numbers and air strikes. Around 160,000 refugees are in the city, including Republican  soldiers. Many try to escape via boats, which are overcrowded and begin sinking in the Bay of Biscay. Republican General Gámir-Ulibarri flies out of the region to France, to re-enter and take up arms again. All major Republican leaders flee the area. Nationalist forces enter Santander at midday and take 17,000 prisoners, but many are executed right away.

Unknown to the Republicans, the Basque fighters have made a secret agreement with the Italian Nationalist soldiers two days earlier. They agree to surrender at Santoña near Santander (close to 30,000 troops and officials), give over their weapons and do no harm to Basque industry. The Basques head aboard two British ships waiting to take them to safety. This becomes known as the Treason of Santoña.

August 27

The Basque troops waiting to leave Santander are captured by Franco forces. They are given the choice of fighting for the Nationalists or being Italian prisoners in Santoña. 22,000 are imprisoned, with half released three months later as they start fighting for the Nationalists. Only 510 are executed. The final prisoner won’t be released until 1943.

August 29

The Republican Army of the East, along with the XI and XV International Brigades, a total of 80,000 men, 90 planes and 105 T26 tanks, have fighting for five days begin the offensive to capture Belchite. The centre and north units only take vacant land, though the southern units have more success and take Mediana, Quinto and Codo. The Republicans surround Belchite itself but the Nationalists are ready to hold out over the forces. The Republicans cut off the water supply to the Nationalists and the 3,800 people in Belchite. September 1

The Nationalists take Unquera in Cantabria, which borders Asturias, as the Nationalists fighting in the north begin the offensive of Asturias. They begin a slow offensive, which will see troops moving less than one kilometre per day in mountainous areas.

The Republican offensive to take the town of Belchite begins, with aerial bombing, artillery bombing and fighting on the ground. The town is surrounded but the Nationalist are desperate to keep their post.

This Week in Spanish Civil War History – Week 57: 14 – 21 August 1937

August 14

The Nationalists are ready to begin their massive new siege to take the north of Spain. The Army of the North of both sides have been assembled throughout the top half of Spain. General Fidel Dávila has 90,000 troops, 25,000 of them through three Italian divisions. They also have a massive cache of weapons, plus the German Condor Legion aircraft, plus Spanish and Italian planes. Their troops are fresh and the Nationalists are ready after the end of the battle of Brunete at the end of July. The Republicans have 80,000 in the region under General Mariano Gámir Ulíbarri. However, their planes are useless, and morale is low. The Basque soldiers included in the numbers are tired and devastated from a loss of their autonomous region and their capital Bilbao, and are already considering surrendering to Italian troops in order to survive.

 The Nationalist 1st Navarrese Brigade attacks the frontlines between Valdecebollas in the Palencia region and Cuesta Labra in order to block Republican troops south of the Cantabrian mountains. This is in preparation to start capturing Republican territories in the mountain region over the coming week and capture the entire Cantabrian region and Santander city on the coast.

August 15

The Nationalist troops advance through Barruelo up to Peña Rubia, Salcedillo, Matalejos and Reinosilla, all mountainous villages, without resistance, with the exception of the Republicans fighting back at nearby Portillo de Suano.

also August 15

The Servicio de Inteligencia Militar (SIM) is created. Having SIM means that secret police activities are now in the control of the government again, rather than Communist and Soviet hands. Political meetings have now been banned in Barcelona, and the constant fighting is undermining the left-wing groups. Barcelona is the central hub for Republicans mixing, with anarchism, socialism, regionalism, and communism coming together to produce infighting. The Republican war effort is hindered by these internal arguments. Peace has not truly been restored in Barcelona since the outbreak of fighting in May.

August 16

The Nationalists take Portillo de Suano and the industrial factory area outside the town of Reinosa during the day, and take central Reinosa at dusk. Meanwhile, the Navarrese Brigade are advancing, furthering the Nationalists’ control of the region. Italian troops sent from Burgos are heading to Lanchares, 17 kilometres from Reinosa, and also San Miguel de Aguayo, a mountainous 14 kilometres trek north from Lanchares. The Cantabrian area is quickly being swallowed by Nationalist troops with little to no resistance in the sparsely populated regions.

August 17

The Republicans still hold Campoo, just 4 kilometres east of Reinosa, with 22 battalions camped there. However the Nationalists have now encircled them completely.

In Barcelona, the Socialist Party and the Communist Party sign a pact to ally as one group, to bring stability to the Republicans’ effort. The Communist party expected a merger, in line with international Communist groups. The Spanish Republican government does not like the idea of the Communists controlling the Socialist party, but the unity pact agreement leaves the groups independent but formally allied, meaning the Communists do not gain any extra control over the government.

August 18

Nationalist forces take the town of Santirude as they surge further north through Cantabria, while the Italians claim San Pedro del Romeral and San Miguel de Luena, only 45 kilometres south of Santander itself.

August 19

Cabuérniga, Bárcena de Pie de Concha and Entrambasmestas all fall to the Nationalists.

August 20

Italian troops claim Villacarriedo and Navarrese forces advance towards Torrelavega and Cabezón de la Sal. Santander is now in sight, just 30 kilometres from Torrelavega. The Nationalists are destroying the northern part of Spain and the Republicans cannot do anything to stop them. The Nationalists have overwhelming support, troops and artillery. The Basque, Cantabrian and Asturian units cannot work together against the speed and power of the Nationalist army. The Basques, having already lost their capital Bilbao, are at the morale limits and begin to mutiny as the Nationalists sweep through Cantabria.
