For the rest of the battle of the Somme, both sides flew in rain, mist, sleet and westerly gales, often at dangerously low heights, to direct artillery and attack troops with guns and bombs. 3 November was a clear day and German aircraft shot down five British aircraft. On the night of 6 November German night bombers hit an ammunition train near Cerisy, which exploded next to a cage for German prisoners of war and devastated the area. Better weather came on 8 November and many German aircraft made ground attacks on British troops, a tactic which the began to incorporate systematically into its defensive operations. The British attempted to divert German attention next day, with bombing raids on Arleux and Vraucourt. The raid on Vraucourt by twelve bombers and fourteen escorts became the biggest air fight of the war, when approximately thirty German aircraft attacked the formation as it crossed the front lines. Most of the bombs were dropped over the target but six British aircraft were shot down and three German aircraft were claimed. Three more British aircraft were shot down later in the day; one pilot was killed, one wounded and an observer were wounded in aircraft which returned.
