AbstractPhillipp Schneider, German-American Civil War soldier and resident of Wisconsin since the age of 9, wrote 45 letters from March 1864 to August 1865, totaling ca. 22,500 words. I analyze these letters from a sociolinguistic perspective, considering both the unique mix of German and English usage and the socio-historical implications surrounding the letters. These are supplemented for comparison with two letters written by German-American Heritage German speaker and soldier, Jacob Goelzer, who wrote to Schneider’s sister twice in 1864. I describe the importance of when and under what circumstances these letters were written, and I also delineate instances from the letters of how the dominant community language, English, has influenced the German used and compare the use of German and English.
