The success of the Army of Africa in putting to flight the militias had greatly raised the optimism of the nationalists and the expectations of their allies. Reports were sent to Germany that Madrid had no food reserves, no anti-aircraft defences and no fortifications. The militia were badly armed with old rifles of varying calibres and they had few machine guns that worked. The republican fighters and bombers, consisting mainly of French Dewoitines and Potez, were no match for the Heinkel and Fiat fighters. It was the combination of artillery fire and air attacks which had completely demoralized the militia columns. Even many regular officers began to shake uncontrollably when they heard aero engines.
It is often forgotten that the Spanish metropolitan army had no battle experience and the majority of its officers had not handled troops even on manoeuvres. This lack of training, as much as the instinctive dislike which most officers felt for the militia system, contributed to the chaotic retreat of the republican forces from Estremadura. As headquarters’ staff frequently retreated without attempting to warn their forward units, it was not surprising that militia groups, feeling abandoned, should make a run for it before they were cut off. In fact, with communications virtually non-existent, a formalized command structure could not have co-ordinated the different sectors, even if it had been run efficiently. General Carlos Masquelet attempted to establish defences close to Madrid, with four concentric defence lines, roughly ten kilometres apart. They were not continuous, but concentrated on the most important road junctions.1
The nationalist advance on the capital started at the end of the first week of October. The Army of Africa began a three-pronged attack: northwards from Toledo, north-eastwards along the Navalcarnero road and eastwards from San Martín de Valdeiglesias. Mola was given official command of the Madrid operation, which appears to have been a calculated ploy by Franco, in case anything went wrong,2
while Colonel Varela was in command of the colonial troops. Yagüe was back with the Army of Africa, but in a subordinate position. The columns, composed of around 10,000 men each, were commanded by Lieutenant-Colonels Carlos Asensio, Fernando Barrón, Heli Rolando de Tella, Delgado Serrano, and Major Castejón while Colonel Monasterio commanded the cavalry. The left flank of the attack was strengthened by 10,000 men from Mola’s army, made up of CarlistAfter Navalcarnero on the north-east axis had fallen, Illescas on the Toledo road was occupied on 19 October. Torrejón, also on the Toledo road and some 30 kilometres from the capital, was taken several days later. The nationalists were not alone in believing that Madrid would fall to them rapidly. Foreign journalists and diplomats were sure that the advance of the Army of Africa, backed by squadrons of the Luftwaffe and Italian air force, could not be stopped. The Republic’s administration seemed paralysed by a strange mixture of frantic activity and inertia. Many blamed ‘sabotage by reactionary civil servants’, but however true, such charges did little more than divert attention from the government’s own chaos.
In the second half of October Largo Caballero began to issue decrees extending mobilization in an effort to improve Madrid’s defences; yet for much of the capital’s population the war still seemed remote. Militiamen, criticized for being on ‘excessive guard duty’ in the capital rather than at the front, tended to ignore official communiqués. Nor could the prime minister himself forget old rivalries. He refused to assign UGT construction workers to the digging of trenches in case they defected to the CNT. And yet the speed of the nationalist advance was such that on 18 October, when Caballero had tried to telephone the republican commander in Illescas, he had found himself talking to the nationalist commander who had just occupied the town.
