My grandfather Frank Williams was a pvt. in co B 13 inf P.N.G from 1913 to 1915 at which time he joined the army. He joined the 13th in Scranton PA. Can anyone tell me what kind of company it was ? ( Rifle, M.G., Transport, etc. ) I am looking for a very short history about the 13th in general, and co B specificly, to add to Frank's personal history folder. Thank You Very Much Art Williams
