Please help it is not a multiple answer question just one answer!! The question has been asked many times if I believed then that the Maine was blown up from the outside. My answer to this has been that my first order on reaching the deck was to post sentries about the ship. I knew that the Maine had been blown up, and believed that she had been blown up from the outside. Therefore I ordered a measure which was intended to guard against attack. . . . There was the sound of many voices from the shore, suggestive of cheers.

–Charles D. Sigsbee,
Captain of USS Maine,
1899

The ship blew up in the harbor.
The captain heard voices from shore.
The captain thought he heard cheering.
The explosion came from inside the ship.
