Letters 8-14 were transmitted between December 7, 1942 and January 1944, between Gövsa and İnal.The focus of the seven letters that make up the first group is Muallim Cevdet. On the occasion of a memorial book prepared by Osman Ergin, Cevdet is also brought up with his personal life and personality. The letters in the second group start as two friendly correspondence and evolve into the contentious correspondence of the two biographers. These letters contain important information about the writing phase of Gövsa's Meşhur Adamlar (Famous Men) and İnal's Son Sadrazamlar (Last Grand Viziers) works.
