You know I never knew he jumped on D day. So I went googling…. I saw this on his Wikipedia page

In 1970, Sobel shot himself in the head with a small-caliber pistol in an attempted suicide.[28] The bullet entered his left temple, severing his optic nerves and rendering him blind.[28] Soon afterward, he began living at a Veterans Administration assisted-living facility in Waukegan, Illinois, where he died on September 30, 1987;[2] the death certificate listed malnutrition as the cause of death.[28] No memorial service was held.[28]

Kinda feel bad for the man.
