3. What is war?
War is nothing more than the continuation of politics
by other means.
Karl von Clausewitz
Politics is war without bloodshed while war is politics
War is the point at which politics turns into murder.
Michel Serres, (Le Contrat naturel, 1990)
4. Definitions of War

knowledge and persuasion, or in modern terms
intelligence and diplomacy, interact with military
strength to determine outcomes in a world of other
states with their own “grand strategies.”

15. Origins of World War-1
• Germany, France, Russia, Austria-Hungary, and
Britain attempting to keep the lid on the
simmering cauldron of imperialist and
nationalist tensions in the Balkans to prevent a
general European war. They were successful in
1912 and 1913, but did not succeed in 1914.

30. • The Changing Nature of Warfare
in the 20th Century
31. • Warfare at the beginning of the twentieth
• There had been little change in tactics in land
warfare since the Napoleonic wars
• Commanders still placed a great importance on
the role of the cavalry, soldiers on horseback, as
an offensive weapon.
• There was an increasing emphasis on mass
• Most countries had introduced conscription. The
German army increased from 500,000 in 1900 to
one and a half million in 1914.
32. • The railway system brought faster and more
efficient transport of troops, weapons and
• The light field gun, based on the French 75mm
gun, was standard equipment and could fire up to
20 shells a minute.
• The breech-loading rifle remained the standard
weapon for the infantryman together with the
• The machine gun, capable of firing up to 600
rounds a minute, was in common use. It was
capable of inflicting heavy casualties on the
33. • Warfare at the beginning of the century:
protected by steel more than a foot
• Battleships had rotating, armoured gunturrets and 15 inch guns.
• HMS Dreadnought was completed in
1906. It was powered by steam turbines
making it two knots per hour faster than
its nearest rival.
34. • The submarine was developed at the
very beginning of the twentieth
• The aeroplane was only invented in
1903. In 1912 the British set up the
Royal Flying Corps. No other country
began the First World War with a
properly trained air force.
35. • Changing methods of land warfare: The
First World War
• The failure of Germany’s Schlieffen Plan
led to trench warfare and three years of
• Machine guns accounted for 90% of Allied
victims at the Battle of the Somme, in
• Commanders used the mass infantry
attack across no-man’s land. This resulted
in very heavy casualties on both sides.
36. • The Germans were the first to use
poisonous gas at the 2nd Battle of Ypres,
April 1915. The Allies soon retaliated.
• Gas was unsuccessful because the wind in
France generally blew in the direction of
the Germans, which prevented them using
it very often.
• Both sides used a constant bombardment
of enemy positions before an attack. At
one stage, the Germans had over 20,000
37. • Tanks were first used during the Battle of
the Somme, in July 1916, but were too
slow and unreliable with many breaking
• They proved decisive in the Allied
successes of July-November 1918.
38. • The Second World War
• Blitzkrieg used shock tactics. Motorised
vehicles, tanks and air power were coordinated by radio communications as they
pushed deep into enemy territory.
• Reinforcements would then follow the
advance forces and take secure control of
the territory captured.
• Parachutists were dropped behind enemy
lines to capture bridges and other
important targets and further disrupt
39. • Dive-bombers moved ahead of the tanks and
attacked enemy strong points.
• The French had constructed the Maginot Line.
Hitler’s armies simply by-passed the Maginot
Line by making a daring advance through the
Ardennes region of Belgium in May 1940.
• Blitzkrieg was very effective in the German
invasion of the Soviet Union of June 1941.
• Ultimately it proved unsuccessful due to a
combination of the huge distances involved, the
impact of the severe Russian winter and the
strong Soviet resistance.
40. • Early German Panzer Mark II tanks were
only 10 tonnes in weight and armed with
• Four years later, the Germans were using
Tiger mark II tanks weighing 68 tonnes and
armed with 88mm guns.
• In July 1943, the Germans launched an
attack on the Russians at Kursk. In the
greatest tank battle in history, the Germans
were defeated mainly due to the highly
effective Soviet T34 tanks.
41. • Guerrilla Tactics
• In the Vietnam War, the Viet Cong, led by
Ho Chi Minh, were heavily outnumbered
and outgunned by the US and South
Vietnamese forces in open warfare.
• Guerrilla warfare proved to be a nightmare
for the US army. Guerrillas did not wear
They attacked and then
disappeared into the jungle, into the
villages or into their tunnels.
42. • The Viet Cong fighters were expected to be
courteous and respectful to the Vietnamese
peasants. They often helped the peasants in the
fields during busy periods.
• Similar tactics were employed in Afghanistan by
the Mujaheddin, rebel tribesman who opposed
the Soviet invasion of 1979.
• They successfully attacked Russian supply
routes and shot at their planes. By 1988 they
controlled over 75% of the country.
43. • Changing methods of sea and aerial warfare
• At Jutland the German battleships inflicted
heavier losses on the British. Nevertheless it was
a strategic victory for the British.
• In the early stages of the war, German U-boats
concentrated their attacks on Allied warships.
• From 1916 unrestricted U-boat warfare allowed
Allied ships to be torpedoed without warning.
This proved very effective and by June 1917
Britain had lost 500,000 tons to the U-boats and
London only had six weeks’ supply of food left.
44. • From mid-1917 almost all merchant ships
travelled in convoys. British and US ships
escorted merchant ships in close formation
• Allied shipping losses fell by 20% when the
convoy system was introduced.
• U-boats also played an important role in
the Second World War. During the early
years of the Battle of the Atlantic, U-boats
were able to avoid detection.
45. • Wolf packs of U-boats were able to lie
in wait and torpedo the convoys in midAtlantic. In 1941 the Allies lost 1300
ships rising to 1661 in the following
• From late 1941 onwards, the British
code breakers at Bletchley Park got
better at decoding German codes.
Between May 1942 and May 1943, they
managed to steer 105 out of 174
convoys across the Atlantic without any
interference from U-boats.
46. • Special support groups of destroyers were
created fitted with powerful radar and listening
equipment that could pick up on radio signals
• Between June and December 1943 the Allies
sank 141 U-boats, losing only 57 ships
• Aircraft carriers had been under development
since the First World War
• In November 1940, Swordfish torpedo bombers
launched from the British carrier, HMS Illustrious,
sank three Italian battleships within Taranto
47. • The Japanese navy quickly obtained a full
report and used aircraft from aircraft
carriers to attack the US fleet at Pearl
Harbor, 7 December 1941
• Control of the Pacific was dependant on a
combination of air and sea power. At
Midway in May 1942 when the Americans
destroyed four Japanese carriers, they did
the very thing the Japanese had failed to
do at Pearl Harbor.
48. • Air
• In the early stages of the First World War,
the most important aircraft were airships.
German airships, known as Zeppelins,
were used to bomb British towns.
• The first raids were in 1915.
achieved psychological damage – civilians
in Britain were no longer safe.
• In 1914 aeroplanes were very unreliable
and highly dangerous and were mainly
used for observation.
49. • Soon the ‘dogfight’ had developed, at first
using pistols and rifles but, in April 1915,
the planes were successfully fitted with
• The Germans developed the Fokker fighter
plane with a synchronised machine-gun
mounted in front of the pilot firing between
the rotating propeller blades.
• By 1918 the primitive planes had given way
to sleek fighters such as the Sopwith
Camel and the Fokker Triplane.
50. • The standard German bomber was the
Between December 1914 and
June 1917 there were 57 German
aeroplane raids on Britain, mostly on
London. 5000 people were killed or
wounded by German bombs.
• During the Second World War, air power
now became essential to army and naval
operations. The Polish airforce was
destroyed on the ground in 1939.
51. • The Battle of Britain prevented a German
invasion of Britain. Fighter Command, with
Spitfires and Hurricanes and supported by
radar, was able to fight off the Luftwaffe.
• Britain’s investment in radar in the 1930s
meant that RAF planes were not caught on
the ground as the Luftwaffe approached.
• From 1940 to 1941 the Luftwaffe attempted
to blitz Britain into submission by bombing
major British cities.
52. • Berlin and other major German cities were
bombed regularly from 1943 to 1945 using
high explosive and incendiary bombs
which caused fires to rage uncontrollably.
• German war production was disrupted but
Germany did not surrender. The Allied
armies advancing in to Germany forced the

The V1 ‘flying bomb’ was jet-powered and
filled with a tonne of high explosives. It fell
to the ground when the engine cut out.

Iraqis out of Kuwait and confirmed
the continued importance of land
forces in major conflicts.
61. • Warfare at the end of the twentieth
• By the end of the twentieth century
there were two forms of warfare –
nuclear and conventional
• The destructive power of nuclear
weapons still acted as a deterrent

Evolution of of nuclear weapons
paradigm shift in strategic thinking because
with nuclear weapons “the possible cost are
always much higher than possible gains”.
•Under the shadow of nuclear weapons there
were no victors or losers in war, what was
exclusively unique to this situation was that
there was no effective Defence against these
•This made the nuclear deterrence more
effective and prevented the nuclear weapons
adversaries from taking any irrational steps.
