As Alan’s leave in Sussex comes to an end, he and Lorna become engaged, and he sells his motorbike to buy her a ring. Meanwhile, Harry leaves Becket’s Hill to work in a munitions factory. Triggers is frustrated by the attitude of his commanding officer, until the Major, burdened by the responsibility of his position, takes over Triggers' reconnaissance duties and is shot down and killed. Enraged by the RFC losses against superior German machines, Triggers remembers one of the Major's comments and attempts to ram an Eindecker, but fails to bring it down. On the same day, a general arrives to visit the base, and meets Alan as the latter returns from leave. Triggers' frequent protests to senior commanders at last bear fruit, as the general orders ‘C’ Flight into forward action, with the task of keeping the Eindeckers busy so as to prevent them from shooting down British reconnaissance planes. For the first time in the series, German pilots are shown discussing tactics. All the observers except Bravington are sent away to join the reconnaissance effort, and Triggers introduces a new regime, with Sergeant Mills instructing the pilots in keep-fit exercises. With a new French engine and a Lewis gun fitted to the BE2, Alan is sent to try out a new approach and succeeds in unnerving the German pilots. (thetvdb.com)
