John Gualtier enlisted in the U.S. Army at age 18 and became a medic during WWII. As a teenager, he felt unequipped for the life and death decisions he was making each day. Once, he ran from his cover six times to pull wounded soldiers to safety and then tend to their wounds. They survived, and John was awarded the Bronze Star for Heroism. The Allies won the war, and John's unit liberated a Nazi concentration camp. He was an eyewitness to the horrific treatment of Jewish people there. One Jewish man died in his arms as he tried to feed him. Later, he went to Nuremberg, Germany to be a medic for soldiers guarding criminals during the Nuremburg Trials. Author Imi Duchesneau and illustrator Alyssa Landi have beautifully brought a hero's true story to life for young readers.
