In 1187, the Islamic hero Saladin decisively defeated the Crusader army at the Battle of Hattin and recaptured the holy city of Jerusalem. The news of Jerusalem's fall sent shockwaves throughout Europe. In response, three of Europe's most powerful monarchs—King Richard I of England (known as the Lionheart), King Philip II of France, and the Holy Roman Emperor Frederick I (Barbarossa)—united to launch the Third Crusade. Their singular goal was to retake Jerusalem from Saladin. Frederick I's massive army was the first to march overland, defeating Islamic forces along the way. However, on June 10, 1190, a devastating tragedy struck when the Emperor drowned while crossing the Saleph River in Anatolia. The 68-year-old monarch, exhausted and overheated from a long march under the scorching summer sun while wearing heavy steel plate armor, plunged into the freezing, glacier-fed river. The extreme temperature difference likely triggered a sudden heart attack or physical shock. Furthermore, when his horse slipped and threw him into the water, the immense weight of his full suit of armor dragged him down, making it impossible to swim against the strong current. Without their legendary leader, the formidable German army fell into disarray and largely disbanded, dealing a massive blow to the Crusaders' morale and strength before they even reached the Holy Land.
Meanwhile, the Christian forces had been besieging the strategic port city of Acre for nearly two years but were trapped by Saladin's outer blockade. The tide turned dramatically when Richard I and Philip II arrived by sea in 1191. Richard's brilliant use of siege engines and aggressive tactics finally forced Acre to surrender. However, the joy of victory was short-lived as sharp disagreements arose between Richard I and Philip II. The two kings had long been rivals in Europe over territory, and their animosity intensified during the crusade due to disputes over the division of spoils, who should be the next king of Jerusalem, and Richard's breaking of his betrothal to Philip's sister. Consequently, shortly after the capture of Acre, Philip II returned to France, citing ill health and domestic political duties, leaving Richard to lead the campaign alone. Marching south along the coast toward Jerusalem, Richard faced Saladin's continuous hit-and-run attacks by highly mobile horse archers. At the Battle of Arsuf, Richard maintained a disciplined defensive formation until the perfect moment, then launched a devastating heavy cavalry charge that shattered Saladin's forces, shattering the myth of Saladin's invincibility.
Richard pushed close to Jerusalem but realized that capturing and holding the city deep inland would be impossible due to stretched supply lines and Saladin's scorched-earth tactics. When Saladin suddenly captured the coastal stronghold of Jaffa, Richard launched a daring amphibious counterattack with a small force and miraculously retook it. Exhausted by the prolonged war and holding deep mutual respect for one another's abilities, Richard and Saladin finally agreed to the Treaty of Jaffa in 1192. The treaty recognized Muslim control over Jerusalem but guaranteed that unarmed Christian pilgrims could visit the holy city safely, while the Crusaders retained the coastal cities like Acre. The Third Crusade thus ended not with the conquest of Jerusalem, but with a pragmatic and historic peace.
