With the major offensive on the Somme imminent, Foch told Wilson in May that until the Allies had far more guns and ammunition such an attack was "suicidal", worries which were shared by Clemenceau, who apparently came to Rouen especially to see Wilson. Like many British generals, Wilson himself was overly impressed by the amount of artillery now available and wrote (22 June 1916) "we run a serious chance of doing something considerable here (on the Somme)." IV Corps did not directly participate in the Somme under Wilson's command.
