The officer who stormed Normandy with nothing but a cane and pistol

His citation reads:

He repeatedly led groups from the beach, over the seawall and established them inland. His valor, courage, and presence in the very front of the attack and his complete unconcern at being under heavy fire inspired the troops to heights of enthusiasm and self-sacrifice. Although the enemy had the beach under constant direct fire, Brigadier General Roosevelt moved from one locality to another, rallying men around him, directed and personally led them against the enemy. Under his seasoned, precise, calm, and unfaltering leadership, assault troops reduced beach strong points and rapidly moved inland with minimum casualties. He thus contributed substantially to the successful establishment of the beachhead in France.
