January 1

By the 25th week of the war, neither side would be able to say their plans had been executed the way they hoped. The Nationalists had hoped to invade, take Madrid and rule the nation within weeks or months. The Republicans came together, multiple factions with similar principles, hoping to oust the fascists. At no stage were they prepared enough to see through their goals. 1937 would see Franco’s plans to take Spain become more established. Franco had much help from Hitler and Mussolini, while the Republicans still had the Soviets on their side, due to the large Communist faction in Spain. But with Republicans made up of many groups and no one clear leader, divisions were one of the main forces at play in the war, with Anarchists and Communists splitting constantly from the Socialists and workers’ militias. As with all wars, the regular people were constant losers.

The third battle for Corunna Road, just northwest of Madrid city, commences.  General Orgaz Yoldi has gained more Nationalist reinforcements and begins the offensive, known as the Battle of the Fog. The Nationalists retake the town of Boadilla del Monte, as the Republicans are still suffering from their earlier losses. The Republican have five divisions working together, along with the XIV International Brigades, but have little ammunition and have to surrender the town and that portion of the crucial supply route of Corunna Road.

With surging numbers of Nationalist soldiers coming from the right, the Republicans have to retreat even further away from Boadilla del Monte and also lose the town of Las Rozas, just 11km north of Boadilla del Monte. The weather is at freezing point all day and night and the fog continues to make battle ever more difficult.

The Republicans deploy more units from Pozuelo, ten kilometers west of Madrid city. The Modesto division, a brigade of four units combined, manage to secure the front while other units retreat from advancing Nationalists. The fog continues to thicken, aiding to secure the front for the Republicans and keep the Nationalists at bay, though the strategic towns have been lost. But once the fog lifts, the Republicans know they are in trouble.

As the fog lifts, the Nationalists, with 18,000 troops and air support, attack Pozuelo, where many Republican forces are in retreat. The Republicans run out of ammunition, including for the T26 tanks from Russia, which have destroyed 25 German tanks throughout the day. The Republicans have to scatter, without weapons or communication, being split by the attack. Republican General Miaja tries to get the German Thaelmann battalion of the XIV International Brigade back together, along with Lister’s Communist unit, in order to try to regroup. The Nationalists continue to widen their hold over Corunna Road and also take the opportunity to bomb the city of Madrid, mostly by day.

All of the XIV International Brigades are forced far back from Boadilla del Monte and the Nationalists have Corunna Road. They meet up with other Republican groups and are ordered to retake Las Rozas, but they lack the men or firepower to do so. Among the young foreigner volunteers was untrained machine-gunner 17-year-old Esmond Romilly, nephew of Franco-sympathiser Winston Churchill. (It was rumoured that Romilly was Churchill’s own son, Churchill having bedded his wife’s sister. The sisters’ mother was a notorious cheater, and their real father(s) is unknown. Several men are options, one being the grandfather of young Romilly’s wife – meaning the young couple were first cousins. The rich do like to make their own rules, and the family is fascinating/bizarre.)

The Nationalists bomb Las Rozas from the air, destroying the town and killing almost all the Republicans and International Brigades huddled nearby for safety. The locals of the town have already long fled, hiding in caves in the Hoyo de Manzanares mountains nearby. All but 35 Republicans are killed, those not killed manage to retreat wounded. Those foreigners who survived, such as young Romilly, are sent home with wounds and illness. Romilly went on to write a book named Boadilla, all about the slaughter of  the battle. The Nationalists are in total control of the area, and ready to begin their final push to control all of Corunna road. Both sides have now lost around 15,000 men each.
