 * During a war five regiments marched to new positions in the night.
 * The body stationed at the upper $A$ marched to the lower $A$,
 * that at the upper $B$ to the lower $B$,
 * that at the upper $C$ to the lower $C$,
 * that at the upper $D$ to the lower $D$,
 * and the regiment at the left-hand $E$ marched to the right-hand $E$.
 * Yet no regiment saw anything of any other regiment.
 * Can you mark out the route taken by each so that no two regiments ever go along the same road anywhere?
