The Titanic has been warned throughout the day, and the days before, that there is icebergs ahead, but many of the warnings were ignored or never even made it to the bridge.
Frederick Fleet sees an iceberg straight ahead and sounds the alarm. They attempt to go around it, but the ship is not manageable enough for such a late turn and they hit on the starboard side.
Five compartments are all ready flooded to a depth of 14 feet. Boiler room No. 6 is under 8 feet of water.
