Final answer:
No, in the short story "The Sniper," the fallen enemy did not fire back and kill the sniper upon being turned over; the actual story ends with the sniper discovering the identity of his enemy.
Step-by-step explanation:
In the short story "The Sniper", the answer to whether the soldier, upon turning over the body of the enemy he had killed, was killed himself is no. The text does not suggest that the fallen enemy fired back to kill the sniper. Instead, the sniper faces a moment of revelation and shock upon realizing the identity of the enemy. The texts provided seem to be from various narratives, each depicting tense moments of close encounters with death, but they do not pertain to "The Sniper" by Liam O'Flaherty, which is the story that the question likely references. Therefore, it is important to differentiate between these texts and the specific story in question.
In the story 'The Sniper,' when the sniper turned over the body of the enemy he had killed, the soldier did not fire back and kill the sniper. The soldier was already dead, as indicated by the description of him having about twenty bullet holes but none of them well placed enough to kill him. The sniper then tends to the soldier, giving him water and malted milk tablets to ease his suffering.
