N - Nuts

Napoo:

Gone, finished. From French i'l n'y en a plus, there is no more. British troops in Russia or who had returned from German prisoner of war camps often used nichevo, a Russian word with the same meaning.

Nix:

Nothing, no. From German nichts.

No Man's Land:

The territory between the two front lines.

Non - Stop:

Enemy shell that has passed well overhead.

Number Nine:

Sick. The British army's No.9 was a laxative pill. Handed out indiscriminately by the MO, but especially to those men who were classified M&D (medicine & duty) or NYD (not yet diagnosed). Also known as the Star of the Movies. Gave rise to the bingo caller's expression doctor's orders - number nine, the game itself being one of the more popular respectable pastimes amongst soldiers.
