On the morning of July 9, two Republican brigades attacked at Quijorna, and, after taking heavy casualties, they were able to finally clear the village of Nationalist defenders. On the Republican left flank attacks towards Boadilla del Monte initially made progress, but even though the assaulting units were well supported by tanks, armoured cars and aircraft their losses were so high that the attacks stranded. The fighting continued though, especially on and around the so-called Mosquito ridge in front of the village.
