Scattering operation 28 Jan 1943
In addition, on January 28, 1943 at 11:30 pm the first leaflets were found in two different places in southern neighborhoods of the city, and were turned in to the police. It can therefore be concluded that the distribution of the leaflets could not have begun much earlier than 11 pm. In that case, there would have been so much brisk traffic that the leaflets would certainly have been found had this occurred at an earlier hour. It has not been possible to estimate when the distribution activities ceased the same evening.
