Angelo was awarded the Distinguished Service Cross for his actions during the Meuse-Argonne offensive on September 26, 1918, as the Colonel's orderly with 304th Tank Brigade, commanded by future General George S. Patton, Jr. During the battle, in an exposed position Patton was seriously wounded by a machine gun. Showing great courage under enemy fire, Angelo dragged Patton to safety. He had thus saved the life of a man who would one day become an American legend. In the spring of 1919, an interview appeared in American newspapers in which Patton declared Angelo "without doubt the bravest man in the American Army. I have never seen his equal." According to the interviewer, Angelo began "blushing furiously" as he related the following details:
In 1932, while Patton continued his path on his famous military career, Angelo had returned to civilian life. He was unemployed and suffering along with many other veterans from the effects of the Great Depression. As a result, he joined the Bonus Army movement of First World War veterans demanding monetary compensation for their roles in the war. The particular issue was that these veterans had been promised compensation but they were not due to receive it until 1948. Given the realities of the depression, veterans such as Angelo demanded the money be paid immediately. The veterans marched on Washington D.C., setting up camps in order to protest against the administration of President Herbert Hoover.
Last meeting
On July 28, 1932, troops were ordered into the camps to quell the protest. In the resulting melee, two veterans were killed and many were injured. The commanders of the operation included Douglas MacArthur, Dwight D. Eisenhower, and Patton, the man saved by Angelo so many years before. In the aftermath of the assault on the camps, Angelo approached Patton, but was harshly rejected. The last known words between the men were uttered by Patton: "I do not know this man. Take him away and under no circumstances permit him to return." He explained to his fellow officers that Angelo had "dragged me from a shell hole under fire. I got him a decoration for it. Since the war, my mother and I have more than supported him. We have given him money. We have set him up in business several times. Can you imagine the headlines if the papers got word of our meeting here this morning. Of course, we'll take care of him anyway."
