 In particular, while the nose and tail turrets protected against attacks from the front and rear, the Wellington had no defences against attacks from the beam and above, as it had not been believed that such attacks were possible owing to the high speed of aircraft involved.As a consequence of the losses taken, the tactic of unescorted day bombing was abandoned, and Bomber Command decided to use the Wellington force to attack German communications and industrial targets instead.Another key decision made was to switch the Wellington to night operations; on 25 August 1940, the type participated in the first night raid on Berlin.
