A man sleeps under a bridge in a bedroll that smells of urine, and by the fourth line Dave Bonta has stopped looking at him and started looking at a caterpillar. That swerve is the method of "After the War." The only human details are the word "wino" and the bedroll's military origin, and together they let us guess at a former soldier who has been discarded. The poem never says so, and it doesn't need to. The title does the rest, pointing out that the war is over while its effects are not.
The central image comes from natural history, and an exact one. Certain parasitic wasps lay their eggs inside caterpillars, and the larvae eat the host from within, saving the vital nervous system for last so that the victim stays alive as long as possible. Bonta's wasp larvae start "in at last on the nerve centers, having made / a desolation of the rest." By the time the feeling part of the creature is reached, everything else is already gone. The caterpillar is in its "final instar," the last stage before it should pupate and become something new. That technical term sits oddly beside "wino," and the poem lets the clinical vocabulary stand next to the ruined body without comment. The phrase "the wasp's hungry children" is almost domestic, even tender, and that makes it crueler. The larvae are only feeding. Nobody in this scene is a villain, which may be the most disturbing part.
The second stanza widens the focus with the pronoun "one." The sleeper gives way to anyone, perhaps the reader. "That warm feeling one had taken for love" turns out to be "the fires of corrosion." Judging by the title, that warmth might be loyalty, belief or comradeship, whatever carried a person toward a war, though the poem leaves the "love" unnamed. The word "digestion" echoes the larvae's feeding and suggests a body or a spirit slowly consuming itself while mistaking the sensation for something good.
Then comes the poem's cruelest turn. The phrase "the wrong kind" appears twice, first for digestion and then for metamorphosis, and it quietly implies a right kind, a healing or growth that never arrives. "The very cells are changed, yes," the speaker concedes, almost grudgingly, "but no chrysalis will ever be spun." Change has happened, but it leads nowhere. This denies the consoling idea that suffering transforms a person into something finer.
The form supports this bleakness. There is no rhyme and no regular meter, just conversational free verse with a long first stanza of seven lines followed by three tercets, each shorter and tighter. The whole poem is one sentence, strung together by ampersands and conjunctions ("& that warm feeling," "or the wrong kind," "& the light") and held back from a full stop until the last line. That gives it a drifting, inescapable momentum, like a thought that cannot be put down. Enjambment drags us across line breaks, as in "having made / a desolation of the rest," so that the destruction arrives just after we think a line has finished. Hard consonants recur in "caterpillar," "corrosion," "chrysalis" and "chemical," a faint rasp running under the surface.
The ending leaves the body behind. "The light spreads like a chemical spill / above the river, / blotting out the stars." Light usually promises hope or morning, but here it is a pollutant that erases the stars. The poem doesn't say whether this is dawn or the glare of a city, and the ambiguity helps. The word "chemical" picks up "corrosion" and the altered "cells," so the damage seems to have moved from the man into the world around him.
What makes the poem significant is its refusal of the usual stories. There is no hero, no speech and no explanation of the man's past, only an image so exact and so patient that it shows how slowly ruin can work from the inside.
