Decisive Battles that Get No Love

Some battles are decisive and they know it. Stalingrad, Hastings, Yorktown. Some are game changers and get no love. A couple examples, feel free to add yours (not holding my breath).

1. Manzikert - August 28th, 1071. The Eastern Roman Empire was at it post-Arab invasion apex in 1071. The Macedonian Dynasty had made the "Byzantine Empire" extremely powerful. Emperors Nicephorous II, John I and Basil II had destroyed the First Bulgar Empire and ended the threat from the Abbasid successor states bordering it. The Empire stretched from the Danube to central Syria, Another couple great emperors and all of Syria, Palestine and Egypt might have returned. But the state couldn't handle a string of lousy emperors after Basil II's death in 1025 and a new threat, the Seljuk Turks. In 1071, Emperor Romanus IV tried to meet the threat at Manzikert but was routed and captured. The Seljuk sultan Alp Arslan freed Romanus and asked for a few border fortresses, but Romanus was deposed and blinded when he got back to Constantinople. The Seljuks overran Asia Minor and the bulgars started to flex their muscles. The Empire tried to recover under the Komnenid restoration under Alexius I, John II and Manuel I but could never recover the Anatolian heartland, the heart of the Empire. And Alexius I made the huge blunder of  calling the West for help and leading in 1204 to the Sack of Constantinople.

2. Rocroi - May 19th, 1643. The decisive battle of the Thirty Years War but the battles of Tilly and Gustauvs Adolphus get the ink. By 1643, the Spanish Tercios were the wonder weapon of 17th century war. Mixed pikemen and musketeers, highly organized and trained. Could form squares in defense or smash any battle line. But at Rocroi, the French commander, Louis, Duc du Enhein, used cavalry to surround the tercios and keep them in one place. Then pulverized them with artillery. The Spanish abandoned the suddenly bulky tercio and adapted the battle line line the French and the Swedes before them but it was too late. The big outcome? The French replaced the Spanish as the #1 military power on the European mainland. They would keep that until 1815.
