Long Swords are Ideal
There has never been an arm more revered throughout history than the sword, as the opening quotation and our third entry imply. The club may be more widely used than the most famous blade of monarchs. People are undoubtedly given the impression that an army equipped with long swords would dispatch any line of spearmen in close battle, with the possible exception of a phalanx.
The examination of historical warfare by History.com shows that armies where the soldiers relied on swords were at a significant disadvantage. Even a short sword needs enough of elbow room to be wielded correctly. This is part of the reason why the Roman legion, while engaging their opponents, primarily favoured the short swords known as gladiuses, though even that was largely supported by javelins and slings to pierce opposing lines. In conclusion, unit cohesion in ancient warfare defeated even the most sophisticated individualized weapon.
