History Q;;Ministers of War's Subversion

I've read a LOT of Chinese history, and finished a book this past spring on the Taiping Rebellion, besides 3 others on CiXi, but....I was not getting exactly why the Ministers of War did NOT want Pang to take Suzhou or Nanjing. Why were they subverting his efforts, not giving him what he and his troops needed (like food and proper supplies) so that he could take out the rebels? I understand the Court was full of intrigue and that the Ministers may have had political reasons for wanting Pang NOT to succeed, but what were these reasons?? The only clear mention in the movie is that CiXi would not want an "outsider" to have such power in Nanjing, but how is he an "outsider"? Was he not already assigned to fight the rebels--sure, he was the only one left alive, but that seemed to be because the Ho army, which was supposed to be supporting him, stood by and watched as his people were massacred--and STILL got away with that! Why was Ho not punished? Was it because General Ho seemed to be a favorite of the Court? Someone knowledgeable please explain. Thanks!
