Read it through once

Hunger and misery and sickness and fright and sorrow, and I don't know what all, got so loaded into them that none of them were ever rightly their old selves after the siege. They all died but three of us within a couple of years. One night a shell burst in front of the hole and caved it in and stopped it up. It was lively times, for a while, digging out. Some of us came near smothering. After that we made two openings--ought to have thought of it at first.
