Jackal's Meal: by Gordon R. Dickson
There's no doubt that science fiction has thrown up some appalling militaristic nonsense in its time. Some of it, like Robert Heinlein's Starship Troopers, is redeemable by viewing it across a post-modern line of sight; some, like Joe Haldeman's The Forever War, is just wildly over-rated; some is offensive, like Jerry Pournelle's Jannisaries; and some is sublime, like Adam Roberts' New Model Army. But none of these are as convincing as Gordon R Dickson's various military sf ventures, perhaps because Dickson served with some distinction during World War Two, which adds gravitas to his Dorsai series, as well as a good deal of like detail and characterisation.
First published in Analog in 1969 and collected in The Star Road (Robert Hale, 1975), Jackal's Meal pits military honour against diplomatic expediency. During a conference to debate an alien request for a corridor through Earth-controlled space a strange being is found wandering around the cargo decks of the conference station. It is examined by human doctors and found not to be human, but they conclude it is not alien either. A rumour circulates amongst the station's garrison that the being is a genetically modified human - that it had been a human soldier captured by the aliens and modified for fun or sport. This rumour reaches the aliens, who deny the being was once human, but offer no explanation as to what it is - and so a tense stand-off develops, which must be defused by the diplomatic staff. The garrison is convinced that an atrocity has taken place and is outraged; the aliens view such outrage as an attempt to gain the upper hand in negotiations. The solution, which I won't reveal, is rather affecting and typical of an author who has seen at first hand how codes of honour and sacrifice can be erected as obstacles and traps on a battlefield.
Honourific systems appear to be a long-standing feature in Dickson's work; who can forget his stunning 1951 colony story, The Bleak and Barren Land, in which a human colonist and an alien fight a duel, the purpose of which is to serve legitimacy on the tide of humans to come.
I'm fortunate to have the Robert Hale edition of The Star Road. Hale editions are interesting, and always a welcome addition to my collection. They were printed almost exclusively for circulation in UK libraries; if you wanted to buy a copy of any of their books you had to make the trip in person to the company's office in Clerkenwell. And ask nicely.
