Goshawk Squadron- 9780330235938

Set during the height of World War I in January 1918, Goshawk Squadron follows the misfortunes of a British flight squadron on the Western Front. For Stanley Woolley, commanding officer of Goshawk Squadron, the romance of chivalry in the clouds is just a myth. The code he drums into his men is simple and savage: shoot the enemy in the back before he knows you're there. Even so, he believes the whole squadron will be dead within three months.
