In October General Philippe Pétain began a series of limited attacks at Verdun, each starting with an intense bombardment coordinated by his artillery commander General Robert Nivelle. Then a double creeping barrage led the infantry into the shattered first German lines, where the attackers stopped to repel counterattacks.[6] With repeated nibbles by mid-December 1916 the French retook all the ground the Germans had paid for so dearly. Nivelle was given command of the French Army.[citation needed]
