Burns Phillips Wharf
This wharf was built before the war by Burns Phillips company. After the war, munitions, specifically artillery shells were dumped in this area.
Mustard Gas Dump
Banika maintained large dumps for munitions, including poison gas. Although never used in combat, the American military maintained large stockpiles of Mustard gas in artillery shells and bombs. Its presence was highly secret, but well known to men on the island.
Vincent Butch Bochiaro adds:
"I served in the USN on Baniki from Nov. 43 until Sept 45. I was attached to Mob 10 a hospital unit. Guarded nurses. Drove ambulances and would to hear from one who served there."
Ammo dump fire October 1945
Richard A. Saylor RM3C recalled in a October 20, 1945 letter:
"I was going to tell you about the ammo dump that blew up the other morning. It was about 1:30 in the morning, and the siren started blowing like mad. I had just come off an evening watch, and only just got to sleep. The while sky light up, and the ground shoot so that you could feel the tent floor vibrate. I first thought we would hall have to go fight fire. But, we didn't thou they sure cleared the men out of the bases over there on that part of the island fast. We were safe enough here, but the bad part was that there was two and a half miles of mustard gas, and other gas stored there. Just a good thing the fire didn't get it. It burned up till way after noon the same day. Jim was talking to one of the guys who fought the fire and he said he thought he was lucky to be alive. There were bullets, shrapnel and and everything but no one got burnt. He said it was as bad as any battle. Boy, glad I'm a radio man."
In 1988, an Australian was demolishing these weapons. After the charge went off, there was an almond odor in the air, and he was burned on the face by mustard gas. American military was immediately dispatched to the island to deal with the possibility of more gas. In late January 2006 another mustard gas report was reported and a second team dispatched. They found nothing other than a few conventional artillery shells in a swampy area.
