This last great raid differed from the two previous ones. The battle lasted for some 11 hours and was divided into three different phases. The first one was in the evening and lasted for four hours and concentrated the attacks against the city. The second one was mainly focused on the defending AA artillery, but to little success. The last wave hoped to finally flatten the city, but the majority of the aircraft turned away when met with fierce anti-aircraft barrages and night fighters. The all clear signal was finally sounded at about 6:30 in the morning of 27 February.
