It is wrong to assume that numbering sequences in battalions always followed a sequential pattern. They didn't. As the war progressed and casualties grew, large numbers of men were often transferred from one battalion to another and allocated numbers within blocks which did not fit the sequential patterning seen to date. This becomes particularly evident in most battalions from 1916 onwards. For an example of this, see my post on the 23rd London Regiment.
