Suddenly, 1,500 British Foot Guards under Maitland who had been lying down under the ridge rose and unleashed upon them close range, point-blank volleys, killing 300 with the very first volley alone, resulting in the decimation of a large part of Napoleon's elite infantry reserve, the hitherto undefeated Imperial Guard, followed by a British charge which resulted in the retreat and collapse of the French lines, turning the tide of the Battle into a decisive Anglo-Prussian victory and marking the end of the Napoleonic Wars.
The Battle of Gettysburg (1863) was another example, especially the Union defense against Pickett's Charge, which was greatly aided by the reverse slope of Cemetery Ridge that both protected and hid infantry and large numbers of cannons that could not be easily seen by the attackers.
After the capture of Carentan by American paratroopers, German forces (elements of the 17th SS Panzergrenadier Division and 6th Fallschirmjäger Regiment) counterattacked in an attempt to recapture this strategically vital town on 13 June 1944.
Elements of the U.S. 101st Airborne Division (502nd and 506th Parachute Infantry Regiments (PIR)) met the enemy advance southwest of Carentan at the Battle of Bloody Gulch.
The American troops were outnumbered and being hit with tank and assault gun fire, but the reverse incline enabled them to direct all their firepower at the Germans as they appeared over the top of the hill.
