Among the biographically inspired writings, those that are inspired by the momentary beauty or horror of the experienced events always seem more authentic, they have an atmosphere. This finding is particularly characteristic of Dr. Lajos Somorjai's World War II war diary in Russia. The honest lines of a doctor assigned to a medical column of the 2nd Army, or for a short time to a first-line infantry battalion, were really written close to the front, sometimes in the heat of battle, not after the fact, with due consideration and evaluation of the events that happened to him, the situations he experienced. While writing his diary, he was guided by his first impressions, hopes, disappointments and emotions. The writer of the war diary was first made to think about his truly forced sacrifice, the reason for it, and the possibility of it becoming fatal after the successful attack of the Soviet troops who crossed the Don between August 6 and 9, 1942, and the danger of the front line being breached by the enemy, encirclement and capture. However, his mood and state of mind actually started to become more and more desperate and seething from the end of September, which then reached a critical level in the days immediately before his return home at the end of April 1943. In the war diary, we can read sharp, sometimes ruthless criticism and individual opinions about the management methods of the higher command staff of the 2nd army and the vices of the military hierarchy, unusual in civilian intellectual life. The front diary of Lajos Somorjai is an engaging read, and a document of historical value, from which the former eyewitness or affected relative can reminisce, and the merely interested reader can form a more nuanced and authentic picture of the tragic chronicle of our military participation in the Second World War along the Don. The image reflected by the diary is made especially sensitive by the author's own photos.
