VON EICHBORN: The staff of Army Group Signal Regiment 537 was accommodated in the so-called Dnieper Castle.
DR. STAHMER: Where was the advance unit?
VON EICHBORN: The advance unit may have occupied this building, too—or at least a part of this advance unit did—to safeguard this building for the regimental staff.
DR. STAHMER: Do you know who was in command of this advance unit?
VON EICHBORN: Lieutenant Hodt was in command of this advance unit.
DR. STAHMER: When did this advance unit come to Katyn?
VON EICHBORN: Smolensk fell on about 17 July 1941. The army group had planned to put up its headquarters in the immediate vicinity of Smolensk, and, after this group had selected its quarters, this region was seized immediately after the fall of the city. The advance unit arrived at the same time as this area was seized, and that was probably in the second half of July of 1941.
DR. STAHMER: Therefore the advance unit was there from July of 1941 until 20 September 1941?
VON EICHBORN: Yes.
DR. STAHMER: And the entire staff was there from 20 September 1941?
