No Such Puzzle: Tap Codes

The tap code, sometimes called the knock code, is a way to encode text messages on a letter-by-letter basis. It has been used by prisoners to communicate with each other by tapping metal bars inside a cell. For each No Such Puzzle in August, we provide a tap sequence and an indicator for the number of words in the answer and their lengths. Can you solve the code and identify the prison or prisoner of war camp?
