Trick Question of the day!

I've finally lost my mind. I know others have thought this for years, but
now its official!

In the nation owned pop center are the following commanders:

A - Army Commander

B - In the Army with A

C - Other Army Commander

D - In the Army with C

What is the fewest orders to:

1) Put B in charge of an army consisting of ALL of the troops except
for 100 HI

2) Allow B to do a force march

3) Put C in the army with B

4) Put D in the army with A

5) Leave A with 100 HI

6) Buy food for the army B will command?

WOW!

I tried this once, but the Army of Dwarf Labor and Union protested my use of
cheaper Hobbit workers.

Thanks in advance.
