In December 1943 I had the good fortune when parachuting to incur a minor injury which afforded me a rest from military service. This was extended by a sympathetic commanding officer, who let me remain unemployed until June 1944 when the book was finished. I wrote with a zest that was quite strange to me and also with impatience to get back to the war. It was a bleak period of present privation and threatening disaster — the period of soya beans and Basic English — and in consequence the book is infused with a kind of gluttony, for food and wine, for the splendours of the recent past, and for rhetorical and ornamental language, which now with a full stomach I find distasteful.

It was impossible to foresee, in the spring of 1944, the present cult of the English country house. It seemed then that the ancestral seats which were our chief national artistic achievement were doomed to decay and spoliation like the monasteries in the sixteenth century. So I piled it on rather, with passionate sincerity. Brideshead today would be open to trappers, its treasures rearranged by expert hands and the fabric better maintained than it was by Lord Marchmain. And the English aristocracy has maintained its identity to a degree that then seemed impossible. The advance of Hooper has been held up at several points. Much of this book therefore is a panegyric preached over an empty coffin. But it would be impossible to bring it up to date without totally destroying it. It is offered to a younger generation of readers as a souvenir of the Second War rather than of the twenties or of the thirties, with which it ostensibly deals.
