Knowing My Father: The Collision of the O. B. Jennings and War Knight relates Joe's methodical search to know more about his longlost father. In that search, Joe discovers the tragic story of the fiery collision of the US tanker O. B. Jennings and the British merchant ship War Knight during World War I as their convoy evaded German Uboats in the English Channel. A US Navy armed guard defending the O. B. Jennings, gunner's mate Michael Tedeschi was heroically rescued by the British Royal Navy escorts from the burning sea. Joe satisfies his search to know his father better and, at the same time, reveals and exposes one of the unfortunate naval disasters that occurs in times of war. Knowing My Father serves as a companion to Joe Tedeschi's memoir, A Rock in the Clouds.
