In the Battle of Cynoscephalae, as the Roman left was being pushed back, Titus Quinctius Flaminius decided to charge his elephants into Philip V's disorganized Macedonian left, which had not yet formed a phalanx. As the Macedonian left routed, a Roman tribune took twenty maniples and outflanked the Macedonian right wing, thus ensuring a Roman victory.
In the Battle of Pydna, though the Romans were being pushed back by the Macedonians under King Perseus, the Macedonian line began to lose cohesion since the Romans were retreating into hilly terrain. Lucius Aemilius Paulus saved the day for the Romans when he ordered his men into the gaps in the phalanx, where the Roman gladius and heavy armor prevailed against the Macedonian daggers and light armor.
Hmm, the ones that stand out are the Battle of Lobositz (1756), the Battle of Rossbach (1757), and the Battle of Leuthen (1757).
