Okay, I have finally returned!
*surveys tactical situation*
This sucks. Fortubatly, I still have some Yu Yang archers who didn't go on the assassination mission. They are ordered back to the Fire Nation to rendezvous with Princess Azula, and assist her in maintaining defence and countering enemy spy attempts.
Blockade troops are to begin making raiding parties into known centers of production in the Earth Kingdom, and do some damage. Earthbender auxillary forces are to begin building fortifications near Ba Sing Se. The Imperial Firebenders are to rendezvous with the Air Force, and hold back in reserve, to deal with any further counter attacks.
