[Blood of Tyrants]

Did I read it right? He threw himself on TWO grenades and survived?

[ConorMacNessa]

He threw himself on one, and when the second one was tossed in, he grabbed it and put it under his body.

After the war and after he finished college he signed up with the Army and served with the 82nd Airborne where he rose to the rank of Captain. On his first jump, both his main and reserve chutes failed and he managed to survive that impact as well.

He was one tough customer!

America demands Justice for the Fallen of Benghazi!

O stranger, tell the Lacedaemonians that we lie here, obedient to their command.

Listen, O isles, unto me; and hearken, ye people, from far; The LORD hath called me from the womb; from the bowels of my mother hath he made mention of my name. (Isaiah 49:1 KJV)

So it would seem!
From his Wikipedia entry:

His companions had thought he died in the blast, so they left him, but he was amazingly still alive. Severely wounded in the right arm and wrist, right leg and thigh, and chest, Pvt. Lucas had undoubtedly saved his companions from serious injury and possible death.[2]

He was evacuated to the hospital ship Samaritan, and then treated at various field hospitals prior to his arrival in San Francisco, California on 28 March 1945. He eventually underwent 21 surgeries. For the rest of his life, there remained about 200 pieces of metal, some the size of 22 caliber bullets, in Lucas' body — which set off airport metal detectors.[4]
