Tasked with protecting First Lady Jackie Kennedy, Secret Service agent Clint Hill was the man standing between her and gunfire the day her husband was killed.

Now, nearly fifty years after the shooting, Hill has written a memoir, Mrs. Kennedy and Me: An Intimate Memoir, about his encounters with the first lady.

The book includes a detailed account of the harrowing minutes before and after the shooting of President Kennedy. Hill also spoke about the day on NBC's Today show.

Here are some of the most chilling moments.

"Her eyes were filled with terror," Hill wrote about First Lady Jackie Kennedy. "She was reaching for something. She was reaching for a piece of the President's head."

The gunshot was deafening, Hill writes. "The impact was like the sound of a melon shattering onto cement," he said.
