The author returns to the question of what function did the lieutenant colonel of the General Staff, Ferdinand Čatloš, hold during the mobilisation in the fall of 1938, before becoming the military representative at the Slovak autonomous government. There are two different opinions. According to the first one, he was the Chief of Staff of the Border Area 37, defending the state border fortification, and according to the second one, he was the Chief of Staff of the 8th Division created during mobilisation as a new one. The author has been dealing with the question of Ferdinand Čatloš’ allocation since 1997. Originally he believed that he was the Chief of Staff of the Border Area 37. However later on he discovered documents, proving that Čatloš was in fact the Chief of Staff of the 8th Division. These documents include mainly the personal files of officers of the Border Area 37 and the 8th division.
