The following is an analysis of personal letters sent by Arthur Yena to his sister, Anna Yena, between 1942 and 1945 while Arthur was deployed to North Africa and Italy as a cryptographer in World War II. This analysis was completed as a senior project by Alexander Lataille at Lyndon State College in 2010. In the immediate section below, the full text of the document is available. At the end of the document there is a section with all the supporting materials, databases, trackers, and literature review documents that were used to support and supplement the analysis. An example of one of these letters can be found below and additional pictures are found in the two immediate links below.
