A king has 9 soldiers on each side of his castle, doing guard duty.

Part 1:
War breaks out, and he needs 4 of these men to go fight. He still wants 9 men guarding him on each side, with men in the centre and sides positions as originally. How does he do it with the remaining men?
Part 2:
They win the war, and the 4 men came back to guard duty. But for safety reasons he wants an additional 4 men guarding him. He still wants only 9 on each side etc. etc. (as part 1), but with the four additional men added to the original amount of men. How does he organize the men?
