The following account is extracted from the 1912 memorial book Sinking of the Titanic, by Jay Henry Mowbray.  The information would have come from newspaper articles published immediately after the disaster, however, the exact articles have not been pinpointed:

"It was close to midnight, and I was on the bridge with the second officer, who was in command.  Suddenly, he shouted 'Port your helm!'  I did so, but it was too late.  We struck the submerged portion of the berg."  (page 46)

"There is no way of telling the approach of a berg, and, besides, I do not intend to go into that now.  We struck, and we paid dearly for it, and that is all there is to that now.  We were running between twenty-two and twenty-three knots an hour.  It seemed incredible that much damage had been done at first, we struck so lightly.  There was a little jar.  Almost immediately, though, Captain Smith rushed to the bridge and took charge.  Afterward I saw Murdoch, standing on the first deck.  I saw him raise his arm and shoot himself.  He dropped where he stood.

As far as Mr. Bruce Ismay goes, he was in the second boat that left the Titanic.  The first boat swamped.  I am sure of that, and Mr. Ismay was bundled into the second boat, regardless of his protests, to take charge of it in place of First Officer Murdoch, who had shot himself.

When the Titanic started to sink Captain Smith was on the bridge.  I saw him.  The first lurch brought the bridge almost under water, and the captain was washed off.  He clambered back, and must have been there another ten minutes.  When the bridge sank slowly down and he was washed off for the second time, a boat tried to make back to him, but he waved for it to keep back.  The last anybody saw of him he was fighting his way back to the Titanic.  He drowned fighting to reach her.

J. Bruce Ismay never showed himself once during the whole voyage and on the Carpathia.  We never saw him from the time the vessel took up the survivors until we reached the dock.  Personally I do not think that Captain Smith was responsible for the high rate of speed at which the Titanic was traveling when the ship foundered.  I kept a record during the voyage.  From noon of Saturday to noon of Sunday the Titanic traveled 546 knots.  I believe they were trying to break records.  When the crash came the boat was traveling at top speed."  (page 87)
 
 

The following account is extracted from the 1912 memorial book The Sinking of the Titanic and Great Sea Disasters, by Logan Marshall.  The information would have come from newspaper articles published immediately after the disaster, however, the exact articles have not been pinpointed:

As Moody's eye lost sight of the skipper in this confusion of waters it again shifted to the bridge, and just in time to see Murdock take his life.  The man's face was turned toward him, Moody said, and he could not mistake it.  There were so many gleaming lights on the ship, flickering out like little groups of vanishing stars, and with the clear starshine on the waters there was nothing to cloud or break the quartermaster's vision.

""I saw Murdock die by his own hand," said Moody, "saw the flash from his gun, heard the crack that followed the flash and then saw him plunge over on his face."
