seven months of the war quite four hundred thousand in prisoners, and
perhaps three-quarters of a million in other casualties, her strength
of somewhat over three millions was maintained at the close of the
first period.

In the same way drafts had further maintained the British numbers. The
French had lost not more than one-fifth of a million in prisoners, and
perhaps a third of a million or a little more in killed and
permanently disabled--that is, unable to return to the fighting line.
In the case of both the French and the British sanitary conditions
were excellent.

You have, then, quite 35 for your number in the West, and quite 33 for
your number in the East of the Allied forces at the end of the winter;
but of your enemy forces you may safely deduct 45-50 might be a truer
estimate; and it is remarkable that those who have watched the matter
carefully at the front are inclined to set the total enemy losses
higher than do the critics working at home. But call it only 45 (of
which 5 are prisoners), and you have against the 68 Allies in East and
West no more at the end of this second period than 75 of the enemy.

The following diagram illustrates in graphic form the change that six
months have produced.

In other words, at the end of the winter and with the beginning of the
spring, although the enemy still has a numerical preponderance, it is
no longer the overwhelming thing it was when the war began, and that
change in numbers explains the whole change in the campaign.
