General Chevert was ordered to flank the Hanoverian position with four brigades of troops from Picardy, la Marine, Navarre, and Eu. At 9 AM, this force advanced toward the Obensburg in three battalion columns and quickly overwhelmed the "Jäger (German light infantry - derived from hunters)" . The Duke of Cumberland, seeing his position threatened from the rear, ordered his reserves and the grenadier battalions protecting the guns to recapture the Obensburg. The use of these grenadier battalions in the counterattack on the Obensburg meant that they were no longer available in the center when the main French attacks went in against the Hanoverian center.
