In the last stretch of World War II, a young German boy named Siegfried Laier was befriended by an American soldier named Alexander who was in Moerlenbach, Germany, to distribute medical supplies and food with the rest of his unit. For whatever reason, Alexander took a special interest in the little boy and his family, and despite the language barrier (Siegfried didn't know any English and believed that Alexander didn't know any German) the two became fast friends as Alexander visited his family every day to check in. Alexander would even take Siegfried along on patrols around town, which made Siegfried feel special since he was the only child in town who got that privilege. This continued for a few months until Alexander and his unit had to leave Germany. While Siegfried had to say goodbye to his American soldier friend, he never forgot him and his kindness toward his family and hoped he would see Alexander again one day. At the time, Alexander was estimated to be around 20 years old, which would put him well into his 90's today if he's still alive, and Siegfried was able to remember the day that the American troops arrived in town. Despite that detail being available and a picture of Alexander and his young German friend being shown on Unsolved Mysteries, the two have not been reunited, yet he said he will never forget his guardian angel.
