This is Ted Roosevelt Jr., son of the President for whom he was named after.
On D-Day during WWII, he was 56 years old. He had a heart condition and he had arthritis. The arthritis forced him to use a cane.
But he was a general and he wanted to lead his troops. So lead he did.
With a pistol in one hand and a cane in the other, he became the only General to land with the first wave of troops from any of the allied beaches.
He would earn a Medal of Honor for his actions.
