On November 6, 1842, Griswold visited his wife in New York after she had given birth to their third child, a son. Three days later, after returning to Philadelphia, he was informed that both she and the infant had died. Deeply shocked, Griswold traveled by train alongside her coffin, refusing to leave her side for 30 hours. When fellow passengers urged him to try to sleep, he answered by kissing her dead lips and embracing her, his two children crying next to him. He refused to leave the cemetery after her funeral, even after the other mourners had left, until forced to do so by a relative. He wrote a long poem in blank verse dedicated to Caroline, titled "Five Days", which was printed in the "New York Tribune" on November 16, 1842. Griswold had difficulty believing she had died and often dreamed of their reunion. Forty days after her entombment, he entered her vault, cut off a lock of her hair, kissed her on the forehead and lips, and wept for several hours, staying by her side until a friend found him 30 hours later.
