Kim, If the patch indeed was a Second Infintry patch, your grandfather served with one of the best units involved in WWII. I have a great uncle that unit, he told me only yesterday of just a few things they did over there. He is sick and not expected to live much longer and I broched the subject of him writting his experiences down on paper and I doubt if he does but he explained that they were second wave into Normandy on D-Day. They fought all the way into Germany including at the battle of the Bulge infact they meet up with the Red Army in Germany. They liberated atleast one of the Death Camps. That fact I learned from another family member as he will not talk much about it. I have a question though. Is your grandfather still alive?
