Daniel Judson Callaghan was a U.S. Navy Rear Admiral during WW II. In 1942, he commanded the USS San Francisco into battle against Japanese forces in the Solomon Islands. He received a Medal of Honor for his heroism on the night of November 12, 1942, despite his death. In the description of his Medal of Honor, it tells how Callaghan, "led his forces into battle against tremendous odds...." In the face of great and powerful enemies, Callaghan continued to fight until the last.
In The Book Thief, Hans Huberman shows many similarities with Admiral Callaghan. He showed many acts of courage and bravery in the face of a powerful enemy. When the parade of Jews went through Molching, "Hans Huberman held his hand out and presented a piece of bread...Hans Huberman was whipped on the street." Even though Hans knew that his actions would have major consequences for himself, he did what he felt was necessary for the dying Jewish man to find peace in his final moments.
