For the Greeks, a hoplite was only as strong as the hoplite next to him; without hoplites on the sides, both flanks were exposed, and heavy infantry units are not mobile. Thus, they implemented the phalanx formation, one of history’s most important military innovations. The phalanx was a line of infantry as wide across as the battlefield dictated, anything from five to 30 men deep, with each rank of men officered by a veteran. The formation also included an additional, expert file-closer at the back of each file, to keep the formation cohesive. The phalanx advanced slowly to maintain its tight formation and unit cohesion, speeding up in unison just before reaching combat.
While the Roman army is rightly famed as an institution, the image of the individual legionary is also an iconic one. The uniformed, disciplined soldier of the late Republic and early Empire is one of the first things many people imagine when they think of Rome. They are the ultimate image of the ancient soldier, their arms and armor instantly recognizable. Their abilities, not only as warriors but also as engineers and administrators, have made them role models for other soldiers through the centuries. In the same vein, their commanders are still celebrated and studied, and generals the world over have tried to emulate the likes of Julius Caesar.
If anything, the one aspect of the Middle Ages that has been romanticized is medieval warfare. Indeed, the Middle Ages have long sparked people’s imaginations thanks to imagery of armored knights battling on horseback and armies of men trying to breach the walls of formidable castles. What is generally forgotten is that medieval warfare was constantly adapting to the times as leaders adopted new techniques and technology, and common infantry became increasingly important throughout the period. By the end of the period, warfare was radically changing thanks to the rise of gunpowder weapons and artillery.
