The success or failure of these campaigns often determined the future of nations and empires. From ancient civilizations to medieval kingdoms, royal armies have played pivotal roles in defending their realms. This article explores some of the most notable military triumphs of royal armies in their defense of territories, highlighting the strategies, leadership, and the far-reaching consequences of these victories.

1. The Defense of the Great Wall of China (Various Dynasties)

Era: 3rd Century BCE to 17th Century CE
Famous for: Protecting China from nomadic invasions

The Great Wall of China, one of the most iconic structures in history, was built to protect the northern borders of China from invasions by nomadic tribes from the north, particularly the Mongols and the Xiongnu. Over the centuries, various Chinese dynasties, including the Qin, Han, and Ming, relied on the royal armies to defend this massive fortification and its surrounding regions.

Military Triumphs

• Ming Dynasty (1368-1644 CE): One of the most notable military efforts to defend China’s borders was during the Ming Dynasty, which saw significant efforts to reinforce the Great Wall. The Ming army, under the leadership of emperors like Zhu Yuanzhang, employed skilled military tactics and engineering to fortify the wall with watchtowers, garrisons, and troop stations.
• Battle of Tumu Fortress (1449 CE): In this battle, the Ming army faced the Mongol forces, who had launched an invasion into northern China. Despite being heavily outnumbered, the Ming forces managed to hold their ground and repel the Mongols. This victory was a significant triumph in the defense of China’s northern territories.

Impact

• The successful defense of the Great Wall played a crucial role in the preservation of Chinese culture, stability, and economic prosperity. The wall not only acted as a physical barrier but also symbolized China’s resolve to protect its sovereignty from foreign invaders.
• The military prowess demonstrated by the royal armies during these campaigns reinforced the strength of the Chinese empire and ensured its survival in the face of external threats.

2. The Battle of Agincourt (1415 CE) – The English Army’s Triumph

Era: 1415 CE
Famous for: Defeating a larger French army during the Hundred Years’ War

One of the most famous military triumphs in the history of royal armies occurred during the Hundred Years’ War, a series of conflicts between England and France. The Battle of Agincourt, fought in 1415, is a prime example of how royal armies can successfully defend their territory against overwhelming odds.

Military Triumph

• King Henry V of England: Leading his army of approximately 6,000 men, King Henry V faced a much larger French force of around 30,000 soldiers. Despite being outnumbered, the English army, primarily composed of longbowmen, used innovative tactics to gain the upper hand. The terrain, a muddy field, played to their advantage, as the French cavalry and knights struggled to maneuver.
• Tactical Innovation: The English army formed a defensive position using stakes to protect their archers from cavalry charges. The longbowmen, positioned in a dense formation, launched a barrage of arrows at the French forces, causing chaos and disarray among the enemy ranks. The English forces used their superior archery skills to decimate the French army, killing thousands and capturing key leaders.

Impact

• The victory at Agincourt was a significant moment in the Hundred Years’ War, as it solidified King Henry V’s position as a powerful military leader. The battle also demonstrated the effectiveness of the longbow, which would become a vital weapon in future conflicts.
• This triumph allowed England to maintain a foothold in France, leading to temporary territorial gains and influencing the course of European history.

The Persians, who vastly outnumbered the Greek forces, landed at Marathon, a plain near Athens. The Athenian army, led by General Miltiades, made a bold decision to engage the Persians in open combat.
• Strategic Positioning: Despite being heavily outnumbered (with around 10,000 soldiers versus 25,000 Persians), the Athenians used their superior knowledge of the terrain and their highly disciplined hoplite soldiers to their advantage. They executed a clever double-envelopment strategy, surrounding the Persians on both sides and attacking at the right moment.
• Victory Against All Odds: The Greeks defeated the Persians decisively, killing thousands and forcing the remainder to flee. The battle was a testament to the effectiveness of Greek hoplite tactics and the courage of the Athenian soldiers.

Impact

• The victory at Marathon prevented the Persian Empire from gaining a foothold in Greece, protecting the future of Greek civilization. It also boosted the morale of the Greek city-states, which would later unite against the Persians in subsequent battles.
• Marathon became a symbol of resistance against tyranny and is still celebrated as a key moment in the defense of Greek territory.
