By August 2008 the French mission was facing serious challenges. A shocking ambush in Surobi, the district of Kabul Province they were responsible for patrolling, killed 10 French troops. The Surobi massacre spurred a larger debate in France about the war. After taking over from the U.S., which exercised partial control over the province for several years beforehand, the French continued to follow the U.S.-led approach of sending troops through an area to kill or chase away militants. Like the American military, the French never developed a solid plan for consolidating their victories and building on successes – which left many areas of Kapisa in a constant tug-of-war between the French and the insurgents.
