14 29 148 October and November ...

12 23 90 In considering the above table it should be pointed out that a large proportion of the losses shown under the heading "Ships unescorted" took place amongst ships which had either dispersed from a convoy or which were on their way to join up with a convoy at the port of assembly.

It was unfortunately quite impossible to provide escorts for all ships either to their ports of discharge or from their loading ports to the ports of assembly for the convoy, as we had so few vessels available for this work.

Thus, in the month of November, 1917, out of 13 vessels engaged in the main oversea trade that were lost, 6 were in convoy, 5 had left or had not joined their convoy, and 2 were not joining a convoy and were unescorted.
November was the month of smallest British losses during the period of unrestricted warfare in 1917, and it is of interest to examine the losses for that month.

The total number of ships lost was 51.
