There is no real boundary between a man resigning and a man being dismissed, I have recorded the reasons as given in ADRIC records for their leaving the force.. One can compare the resignations with the arrivals of new men
To followed the ups and downs of numbers, the 769 leavers occur by month as follows. No date given in the registers 12 men. Most of these seem to be in the first few months of the ADRIC's existence. The table below is an analysis of the men by month of departure
