Philippe Contamine is not of this opinion: "On the face of it, his opponents did not have a clear numerical superiority". It is said by William the Breton, chaplain to Philip at the Battle of Bouvines, that the lines of soldiers stood in line in a space of 40,000 steps , which leaves very little clearance and predisposes to hand-to-hand fighting . William the Breton also says in his column that "the two lines of combatants were separated by a pretty small space". Philip Augustus had then launched an appeal to the municipalities in northern France, in order to obtain their support. 16 of the 39 municipalities of the royal demesne answered the call to arms.
