1918 broken poppies Q and A

What happened in the cave that would haunt Henry for the rest of his life?

Each day after school Henry and his cousin George would go to a cave and play. Then one day they started digging and when George went out some pebbles started falling. Then Henry got stuck in pebbles and stones. When George found him he fell on him in sadness. Just then Henry started coughing and breathing that had haunted him for the rest of his life.

Why did Henry not enlist at the same time as George and how did he feel about that?

Henry did not enlist at  the same time as George because he did not want to go and sleep in the ground. But he felt bad that George went without him and he had kept it a secret till the last second and Henry still had to help on the farm.

What did Henry learn during his training and how was it different from what he thought he was going to learn?

Henry thought he would use weapons in the training, but but they actually learnt more about underground stuff which put Henry´s fear to the test.
