Lecture 2

As technology changes, the way war is fought changes. Tactics change, balance of power changes, HISTORY changes.

Gunpowder

From china, who used it as fireworks. Europe made weapons. Napaloean mastered the

techniques for guns, which was why he was so successful.

Civil War

Technological innovations spawned from industrial revolution. Cotton gin, looms, plows,etc. Southern economy boomed, and political prowess greater. Slavery was vital, and

southern states would never abolish it.

“Cotton is king, and the African must be a slave or it will be the end of all things.”

1820 – Missouri slave state or free state? Worked on compromise (MissouriCompromise), the days of compromise were coming to an end. Passionate debates

rocked the nation.

Southern states succeeded from the union. Firing on fort sumpter—civil war began.

Both sides believed war would be easy and quick. Wrong.

First use in warfare:

Telegraph, railwords, rifles, artillery, gatling gun, telescopes, land mines, ironcladwarship, submarines. The intensity of firepower increased dramatically.

The repeating rifle could fire 10 times faster than normal rifle.

Soldiers were now too powerful. New tactics needed to be developed.

1863 – Picket’s Charge—Lee made a big mistake. Made a frontal assault, which is bad.

Since union soldiers were ready with cannons lined up, now more powerful than in other wars. General Lee was advised NOT to do it! Lee overruled it, he was overconfident.

Thousands of southern soldiers died.

His men marched in perfect formation, right into the cannon fire. Union artillery fire at

them, like shooting fish in a barrel. Marching in formation is not good. Trench warfare

replaced it. There were also intense navy warfare. Ironclad warships were built. 1862,the Monitor was built (union) to counter the Merrimack (confederate), they fought

together to a stand off. A week after this battle, England got word—their whole wooden

fleet was now obsolete!



The Monitor sank, and today it is below the sea.

The Alabama (privateer from south) was used to sink many union ships.

The submarine was built (CSS Hunley) in 1864. They brought a mine to a ship, both ship

and sub sank!

Red means it made a big impact in the war.

Battlefield awareness is also very important. Sensors are used for this. For years, thiswere Eyes and ears of cavalry.



Gave precise and timely information about union forces.

Cavalry is seen here in red. Lee had a great advantage, since he had eyes and ears and

senses of the battlefield.

Lee’s defeat at Gettysburg was due in part to incomplete intelligence from the calvary.

Mead (union) made a gut decision the night before Gettysburg, even against advice. He

said he would fight it out. Imagine if he took that advice, how history may be different.

Balloons were used to report what was beyond the hill (telling back through telegraph).

Sharp shooters always tried to shoot these down.

Also, spying was used. Pinkerton (hired to do this) had bad intelligence. Good leadersare needed to act upon information. Information needs to be passed to commanders and



troops in a timely matter. The telegraph was used in commerce, military leaders used it

in civil war, and became ubiquitous.

General Grant—instinct to use telegraph.

Suddenly, encryption was needed:

A cipher wheel, which encrypts telegraph signals.

Intelligence graph:

The 3rd major component of military is mobility: Supplies and troops. Steam trains and

steam ships played a big role.



River boats were used too.



Military effectiveness is also about moral. In the civil war, music played a role. Ballads

were played, and both armies would stop shooting while played. General Lee: “I do not believe we could have an army without music.”

Marching songs, grassbands…

The union had great marching songs.. is this why they won?

Battle hymn of the republic.



Disease led to creation of Medical units for soldiers, and red cross. Clara Barton startedthe red cross.

Made real hospitals. There were great nurses, including Walt Whitman:



Civil war: it was lucky that we did not destroy ourselves.

World Military Power

The tactics used in civil war became world standard, for at least 70 years, until tanks and bombers became prevalent.



The machine gun was developed further.

The evolution of the technologies.

The civil war battles (after Gettysburg) were fought in trenches.



WWI started in trenches (for 1 year). The allied generals were frustrated, and tried to

charge the German trenches. 400000 troops attacked Germans in trenches. Attack center of best fortified decision. It ended in catastrophe. These kinds of charges are obsolete,

since machine guns. Allied troops cut to shreds.

British lost 400000 men. French lost 200000. WWI continued for another 2 years. The

battle of the sun was a disaster. Over 1 million people total died. Both sides returned to

trench warfare.. until US entered and tipped balance to allies.

The submarine caused Germany to lose war. Germany would sink any vessal

approaching England. US would not tolerate this. Lucitania was struck by German U- boat, and then struck again. It sunk. 1198 innocent people were killed.

This assault on unarmed ships eventually brought US against Germany, and eventually

defeated Germany.
