after the Entente was signed changed attitudes: ‘the French General
Staff welcomed the prospect of British aid, but made no alterations in
their plans because of it’.
11
Plan XVI, however, drawn up in 1907/8,
allowed for adding ‘British contingents’. The French settled the area of
concentration for these contingents without any reference to their ally,
although the British General Staff with Foreign Office permission furn-
ished troop tables over the years, which showed that four infantry divi-
sions and a cavalry division (110,000 men) would be in France by the end
of the eighteenth day after mobilisation.

Joffre’s Plan XVII, the strategic
plan with which France began the war, was developed on the hypothesis
that Germany would be the enemy and that Britain would join France if
war came. When he presented his plan for approval to the Council for
National Defence in January 1912, Joffre included in his estimation of
land forces that ‘we could count upon six infantry divisions, one cavalry
division and two mounted brigades’.
So the finalised plan (submitted in April 1913) expected Britain to
concentrate its Army on the extreme left echelon, two days’ march away
from the French concentration area, and to be in position by the fifteenth
or sixteenth day after mobilisation. However, Joffre wrote later: ‘I was
conscious ... that sin ce the agreement of Great Britain was problema-
tical and subject to political considerations, it was impossible to base
a priori, a strategic offens ive upon eventualities which might very well
never mater ialize’. The small size and conditional presence of the British
forces partly explains wh y L ondon had no precise details of the French
plan. Yet, despite the drawbacks, Britain’s goodwill was highly desirable.
At that 1912 meeting of the Council of National Defence Joffre was told
to avoid any violation of Belgian neutrality, which might lead to ‘with-
drawal of British support from our side’.

Yet no formal alliance, such as bound France and Russia, impelled
Britain to take up its allocated position. If Britain decided for war in
August 1914, it was not from any moral commitment to France, but in
order to protect its own great power status. In any case, treaties could be,
and were, broken: Italy’s membership of the Triple Allian ce did not
prevent its decision to join the Entente in 1915; and Russia’s revolutionary
leaders had no hesitation in renouncing the Pact of London signed on
1 September 1914 in which the Entente powers agreed not to sign a
separate peace or press for peace conditions not agreed by their partners
in advance.
