On April 14, 1912, the RMS Titanic collided with an iceberg, kicking off one of the 20th century’s most devastating civilian catastrophes. The starboard side of the Titanic brushed up against the iceberg at 11:40 p.m. the night of April 14, causing enough damage that at least five watertight compartments in the hull began to fill with water. At about 2 a.m., the ship’s bow had tipped so far beneath the surface that its stern was partially above the water, and at 2:17 a.m., wireless operator Jack Phillips transmitted one last distress call.
