Portland Oregonian, April 27th 1912, interview with Mrs. Warren:
  "Continuing up to the boat deck we tried to get out on the port side, but we were unable to open the door. Noticing the starboard door standing open we went out that way. This boat deck was the top deck of the vessel, uncovered and only a few houses on it, such as contained the gymnasium, a lounge etc.
    At the time we reached this deck there were very few passengers there, apparently, but it was dark and we could not estimate the number. There was a deafening roar of escaping steam, of which we had not been conscious while inside.
    The only people we remembered seeing, except a young woman by the name of Miss Ostby, who had become separated from her father and was with us, were Mr. Astor, his wife and servants, who were standing near one of the boats which was being cleared preparatory to being lowered. The Astor's did not get into this boat. They all went back inside and I saw nothing of them again until Mrs. Astor was taken onto the Carpathia.
    We discovered that the boat next to the one the Astor's [boat #5] had been near had been lowered to the level of the deck, so we went towards it and were told by the officer to get in. I supposed Mr. Warren had followed, but saw when I turned that he was standing back assisting the women.
    People came in so rapidly in the darkness that it was impossible to distinguish them, and while I did not see him again, I thought that he also was in, as there seemed to be still room for more when the boat was lowered.
    There were according to my recollections, either 35 or 36 people in the boat, and I was not aware that Mr. Warren was not with us until afloat and his name was called with no response.
    The boat in which I rode was commanded by Officer Pitman and manned by four of the Titanic's men. The lowering of the craft was accomplished with great difficulty. First one end and then the other was dropped at apparently dangerous angles, and we feared that we would swamp as soon as we struck the water.
    While drifting around, another boat came alongside us and reported, as I remember, 24 or 25 passengers aboard and but one of the Titanic's crew and no light."
