Looking in before he attempted it he saw an officer asleep immediately below him.

It was the ensign of his own company.

Leaning in he touched him gently.

After one or two attempts, the young officer opened his eyes, saying, "What is it?
It's not morning yet." "Hush, sir," Jack said earnestly; "I am Jack Stilwell of your company.
There is a mutiny, sir, forward.

Please help me in, I want to warn the captain of the ship, and he will know what to do." The young officer leaped from his bunk and assisted Jack to enter.
"I will come with you," he said, hastily dragging on his trousers and coat.
