Introduction

Technology has been an ally of human society since the days humans learned to create fire. From wheels to artificial intelligence, technology has been a boon to human life, well in most cases. But there are instances where science and technology has been used by individuals or organizations to create havoc which impacted societies in a negative manner. One such case is the use of technology in wars and battles for victories and conquests. This blog tries to explain 18 historic battles where a major technology was used for the first time on a major scale which also impacted the world order and left a big legacy behind. From the bronze age to the world wars, these battles are always remembered and studied for their use of technology and impact.

1. Battle of Megiddo – 1457 BCE

The Battle of Megiddo was fought between the Egyptian Empire under Thutmose III and a large coalition of Canaanite vassal states around 1457 BCE. The battle is known for the use of large scale chariot warfare which was implemented by Thutmose through a difficult route for a surprise attack. This led to the Egyptian victory which further resulted in the expansion of Egyptian territory in the Levant. This use of rapid chariot attacks on a large scale involving the element of surprise was later followed for centuries in the Middle East and the Mediterranean.

2. Battle of Kadesh – 1274 BCE

The Battle of Kadesh happened between the New Kingdom of Egypt and the Hittite Empire in 1274 BCE. The leaders of the groups were Pharaoh Ramesses II and King Muwatalli II. Ramesses II led 20,000 men in four divisions and was initially ambushed by Hittites but made tactical maneuvering to push the enemy out of Kadesh, although later the Hittites reclaimed the territory and both the party declared success. It was the first war where chariots were used in a more tactical manner rather than an out and out raid. This war laid the foundation of vehicle warfare involving tactical maneuvering and intelligence ambush, which is evolving even today.

3. Battle of Marathon – 490 BCE

This battle took place when the Achaemenid Empire under Darius I invaded Greece. It was fought between the Persians and the Athenians supported by the people of Plataea. The Greeks under their commander Miltiades, although severely outnumbered, used superior armor, long spears to create a Phalanx infantry formation defeating the Persians killing nearly 6400 of them while losing only 192 Greeks. This victory proved that heavy, organized foot soldiers could topple superior numbers laying the foundation of Greek and Roman military formation techniques.

4. Battle of Gaugamela – 331 BCE

The Battle of Gaugamela was the final clash between Alexander the Great of Macedonia and Darius III of Persia. In this battle, the Macedonians were heavily outnumbered, but Alexander designed a plan where he combined Siege Engines with his infantry and cavalry and defeated the Persians. Instead of attacking straight, the Greeks attacked diagonally in a flexible manner. Alexander even withdrew slightly from his side making a bait for Darius to attack. Then Alexander unleashed his reserve cavalry and infantry creating a devastating blow through different directions and thereby destroying the Persians. Darius fled the ground and the Greeks took control of Persia and its remaining satrapies. This battle used the technology of “flexibility”, “combination of siege machines, cavalry and infantry at a single precise point” and use of “hidden reserve forces”. This battle is one of the most decisive and important battles in the history of mankind, being it for political reasons or military upgradation.

5. Battle of the Teutoburg Forest – 9 CE

This battle is very important as it showed the importance of territorial knowledge in warfare. It was formed between the Roman Empire and an alliance of Germanic Tribes. The Germanic alliance ambushed three Roman legions and their auxiliaries. The alliance used knowledge of the geography of the terrain and implemented a guerrilla based ambush in a dense forest area. The legions were completely decimated and this resulted in the halting of Roman expansion into Germania. This battle showed how a perfect combination of territorial knowledge and guerrilla tactics can cause a fatal blow to a much superior and much advanced force.

6. Battle of Yarmouk – 636 CE

This battle is an important event for the expansion of the early Islamic Caliphate. It was fought between the Rashidun Caliphate under Khalid ibn al-Walid and the Byzantine Empire near the Yarmouk river. Unlike the heavy cavalry of the Byzantines, the Arabs used light, fast cavalry and hit-and-run tactics in the enemy’s flank. The Arabs encircled their enemies and harassed the heavy army by concentrating on weaker zones. The Rashidun Caliphate won the battle through fast and mobile tactics and as a result took control over the Levant regions of Syria, Jordan and Palestine from the Byzantines.

7. Battle of Hasting – 1066 CE

The Battle of Hastings was fought between the Duchy of Normandy and the Kingdom of England. The Normans invaded England under William, the Duke of Normandy. They defeated the Anglo-Saxon army led by king Harold II using integrated use of cavalry, archers, infantry and tactical maneuvers. Here combined arms of heavy cavalry was used unlike the use of combined light infantry in Yarmouk. The knights used heavy armored horses and defence to destroy the Anglo-Saxon Army and William was crowned as the king of England later that year. The difference between the combined arms used in Gaugamela, Yarmouk and Hastings was that in Gaugamela a flexible formation with reserved forces was used, in Yarmouk a light and fast hit-and-run tactics was used and in Hastings a heavy armored structured demolition strategy was used.

8. Battle of Manzikert – 1071 CE

It was an important event in world history where the Byzantine Empire was defeated by the Great Seljuk Empire in Armenia that led to the beginning of Turkic rule in Anatolia. The Turks used mounted archery on horseback and used a similar strategy like Yarmouk but improving it with deception and long range weapons. The large Byzantine Army was surprised with this quick hit-and-runs and got destroyed by the hands of the long range mounted archers.

9. Battle of Ain Jalut – 1260 CE

This battle is known for the first significant defeat of the Mongols. The Mamluk Sultanate used early gunpowder weapons to stop the Ilkhanate faction of the Mongol Empire and halt their advancement in the Islamic heartland. It was one of the earliest mentioned uses of gunpowder in a decisive battle. This battle marked the later development of artillery and mobile firearms which soon replaced the use of archery in the future thus creating a huge impact in modern warfare.

10. Battle of Pavia – 1525 CE

The Battle of Pavia was fought between the Kingdom of France under Francis I and the Habsberg Empire of Charles V. This battle involved the use of handheld arquebuses and field artillery which turned armored knights into history. The European battle doctrine shifted after this battle which slowly led to the decline of the medieval armors. This also shifted the power balance in Europe as the Habsberg Empire defeated the French convincingly.

11. Spanish Armada – 1588 CE

The Spanish Armada was a fleet of 132 ships assembled by King Philip II of Spain to invade England. The fleet had 17000 soldiers and 7000 mariners who aimed to join forces with an army in the Netherlands before invading England. England under Elizabeth I defeated this large armada using a smaller fleet with maneuverable ships and naval artillery to completely destroy the armada. This battle marked a significant change in strategic naval warfare. After that naval warfare would favor firepower and agility, not just humongous fleet size.

12. Battle of Blemheim – 1704 CE

This was an important battle in the War of Spanish Succession where the Grand Alliance led by John Churchill, 1st Duke of Marlborough alongside Prince Eugene of Savoy ensured the safety of Vienna by defeating the Franco-Bavarian army under king Louis XIV of France. This battle marked the use of advanced artillery in a strategic and controlled manner unlike in Ain jalut and Pavia where the technology was more of a surprise element and projectile based un-controllable firearms. This led to the development of precision firearms like assault rifles and sniper rifles in future.

13. Battle of Antietam – 1862 CE

Also known as the Battle of Sharpsburg, the battle took place between the United States (Union) and the Confederate States. The battle involved Rifled muskets and ironclad ships making battles deadlier and navies stronger. It marked Robert E. Lee’s first invasion of the North during the American Civil War. Although the battle was a tactical stalemate, with no clear winner, Lee’s Confederate forces were compelled to retreat back to the Potomac river, halting their advance and preventing European recognition of southern independence. The industrialization of war started after this battle.

14. Battle of Tsushima – 1905 CE

It was the final battle in the Russo-Japanese war where the Japanese Fleet led by Admiral Togo Heihachiro, gave a crushing defeat to the Russian Baltic Fleet. Both sides used modern steel warships heavily armored with turrets for long range artillery, capable of sustained, accurate fire. The artillery could engage enemies over 10 kilometers away with huge precision. Also for fleet coordination, real time radio signals were used by the Japanese fleet to maneuver as a single, cohesive force. This was the first major battle where wireless communication gave a decisive edge leading to Japanese victory. Geopolitically this caused a huge impact on the 1905 revolution in Russia.

15. Battle of Midway- 1942 CE

The Battle of Midway was a major naval battle in the Pacific Theatre of World War II between the United States of America and Japan. In this battle the USA used massive Aircraft careers carrying fighter planes to demolish the Japanese forces. This battle led to the Aircraft Careers becoming the ultimate weapons in future warfare. This also marked a decisive victory for the allies which in turn affected the war in a strategic manner.

16. Battle of Inchon – 1950 CE

It was an important battle in the Korean war of 1950. The United Nation Forces under General Douglas MacArthur used amphibious landing in a heavily fortified port in North Korean control. The battle used amphibious battle techniques and naval gunfire support along with air reconnaissance enabling the UN forces to cut North Korean supply lines and thus causing their defeat. This battle became a model for future amphibious operations.

17. Six-Day War – 1967 CE

The battle was fought between the nation of Israel and the nations of Egypt, Syria, Jordan, Iraq and Lebanon. In this battle Israel launched a preemptive strike to gain air superiority. Israeli aircrafts used precision bombing to destroy enemy airfields on the ground. They also used guided missiles with radar integration to locate, track and destroy aircraft effectively without causing any collateral damage. This led to Israel gaining air superiority in the area and gaining territories like the Sinai Peninsula, West Bank, Golan Heights and Gaza Strip. This battle is an important example of effective use of advanced electronics and communications in air battles to gain air superiority.

18. Battle of Fallujah – 2004 CE

This is an important battle in the Iraq War where the United States of America used large scale drones, sensors and precision weapons in an integrated manner to gather intelligence, detect explosive devices ahead of infantry and target insurgent strongholds with minimal collateral damage. This battle is an important event which marked the advanced use of robotics and drone technology for military surveillance and annihilation of enemies. This battle also marked the way on how 21st century warfare will follow.

Conclusion

Technology has been an integral part of wars and battles and many times the superior technology determined the outcomes. From fast chariots to siege engines, from guerrilla tactics to hit-and-run, from armored knights to advanced firearms, from wireless communications to advanced robotics, the way of warfare has evolved along with technology and will unfortunately continue to evolve with bio weapons, AI and cyber warfare. This blog tries to highlight important events in this destructive evolution. Obviously there are many more battles but could only include 18 till now. Maybe I will include others in a future blog.
