Colonel Potter contacted Sergeant Bartruff about the shelling striking the 4077th. Obviously, Captain Pierce, Captain Hunnicutt, and Corporal Klinger were becoming targets of the surprised shelling near and around the camp. Colonel Potter spoke to Sergeant Bartruff at headquarters over the telephone about the demise ... all to no availability. The Sergeant claimed the Colonel had an outdated SRO Book in reference to the password for official identification.
Captain Hunnicutt and his doctors -- naturally -- helped Private O'Malley move directly to the evacuation bus directly to the cave with the help of a Thomas Splint. Everyone arrived at the cave to avoid the shelling from the North Koreans and the Chinese. Captain Pierce -- much to Colonel Potter's unexpected surprise -- suffered from claustrophobia in the first part of the episode. By the time the shelling became extremely prevalent, Captain Pierce reluctantly entered the cave. Much to his surprise, his patient was not recovering too well from surgery.
Major Houlihan and Captain Pierce took the patient back to the 4077th for a second round of surgery -- all to remove a bleeder inside his body. During the surgery, they played twenty questions -- as a game -- to ignore the shelling that occurred outside the camp. The shelling finally stopped in its entirety towards the end of the episode. The end result: A Fat 10.6!! "A++!!"
