(1.) The enemy's flanks, if uncovered.
(2.) His infantry, when, from any cause, its attack would probably succeed.
(3.) All detachments thrown forward without support.
6. When cavalry has routed cavalry, the victorious squadrons should at once charge in flank the infantry protected by the cavalry just beaten. The great Condé, when only twenty-two years of age, by this means, won the victory of Rocroi.
7. Deployed as skirmishers, by their noise, dust, and smoke, cavalry may furnish a good screen for our movements.
8. Cavalry skirmishers scout their corps, to prevent the enemy reconnoitring it too closely.
9. When a cavalry rear-guard has to defend, temporarily, a defile, a bridge, or a barricade, a part should dismount, and use their carbines till the rest are safe.
So, a cavalry vanguard, by its fire, dismounted, may prevent the enemy from destroying a bridge.
In these, and in similar cases, the cavalrymen should habitually dismount, in order to render their fire effective; acting and manœuvring as skirmishers.
