Explanation:

1. The passage mentions "my burning aircraft" and "an RAF fighter... that had come down." Therefore, "the remains" refers to the remains of Roald Dahl's aircraft (or plane/fighter).
2. The text describes a strip of sand "dividing the front lines of the British and Italian armies." Since Roald Dahl was flying an RAF (Royal Air Force) fighter, "our people" refers to the British.
3. Since the crash occurred between the British and Italian lines, and the RAF fighter belonged to the British side, "the enemy" refers to the Italian army (or Italians).
