fields."So much beauty"，he recalled，"and so much pleasure".He recorded with a connoisseur's expertise(行家专长) such details as the many ways in which soldiers would wish each other good luck，and the degrees of madness that were considered acceptable.

　　He identified with the young soldiers and learned in the first few days that you could not affect neutrality(中立)."If you are neutral，you don't get it，" said he.He generally did not carry a weapon，though on occasion he did fire at Vietnamese in emergencies.The young soldiers，he said，"are my guns".

　　The power of the book，perhaps，comes from Herr's insistence on describing the war，or more precisely his own responses to it，rather than protesting(抗议) against it.It also comes from the ceaseless accompaniment of two elements，drugs and music-more particularly rock music，and especially the music of Jimi Hendrix. Herr himself spent drug­fuelled weekends in a flat in Saigon，staring at an ancient French map of Indochina，and he never caught a helicopter without a Hendrix record.

　　He met soldiers with a left pocket full of Dexedrine，the "upper" officially administered by the army to get them into battle，and a right pocket full of "downers" to get them through it.Dispatches did not come out until 1977，when the country was beginning to keep its mind on other problems，but it did more，perhaps，than any other book to freeze an image of despair and a sense of waste about the war，rather as the trench poets of 1914－1918 did in Britain.

　　Herr also made vital contributions to two of the most influential Vietnam films.He wrote Martin Sheen's voice­over for Francis Ford Coppola's Apocalypse Now and later wrote the screenplay for Stanley Kubrick's Full Metal Jacket. His work，in the book and the two films，has been seen as part of the process whereby the US came to see itself and its history no longer merely through traditional literature，but in sounds and images，in ways that prefigured(预示) the Internet.

　　In 1980 Herr moved to London，where he stayed until he moved back to the US in 1991.It was there that he met Stanley Kubrick，who became a close friend，though Herr warned against doing business with him. Herr wrote Kubrick's biography，but he wrote surprisingly little else after Dispatches.
