Big guns on LZ Pony

On LZ Pony, we had the pleasurable company of a 175mm gun and an 8" howitzer. Don't know who they belonged to, however. Always a thrill to hear and feel a 175mm gun fire. We were at this LZ for only a few days. I do not recall any fire missions. We convoyed up to Phu Cat AFB, loaded up on C-130s and flew to Kontum.
