The leader of the commandos, and the only Israeli killed during the raid, was Yonatan Netanyahu, brother of the current Israeli Prime Minister, Benjamin Netanyahu.
Dora Bloch, one of the hostages was not rescued because she had been moved to a hospital, and was later killed on orders of Ugandan dictator Idi Amin. Three other hostages were killed.
For a wonderful account of the raid, I highly recommend 90 Minutes at Entebbe.
