Comments
What defences had been constructed by 1346, the year of the battle? The town formed a obstacles on the right flank of Edward III's army at the battle. It's hard to believe such a small town could produce sufficient funds from murage to build anything significant.
Coulson writes of the following grant 'clearly not for walling but the same levy authorised for the "relief of their estate" burdened by war costs, sea damage and "lack of wainage".' It seems possible to me that the same is true for Crécy and that no wall was ever intended there.
