Why was there a stalemate

the commanders

the trench system

the machine gun

the failure of the new weapons

mud made cavalry very ineffective

infantry men were expected to go quickly through gaps, imposible with the barbed wire

machine guns were ideal defensive weapons. they could fire up to 600 rounds a minute

they were better defending than attacking

war of attrition

provided a shell, why go out

the german machine gun accounted 90% of that allies victims in the battle of the somme

several new weapons were developed but none made significant breakthrough

the invention of the gas mask reduced the effectiveness of gas (accountable for 4% of deaths)

the early tanks were slow and many broke down. they were not used effectively until 1918

heavy guns could do considerable damage to the enemy but not destroy the barb wire. this meant they had to stay in their position.

the flame thrower was unreliable and likely to explode in front of the soldiers that were using them

the trench warfare was a new way of fighting, no one knew how to win a war like this

generals had to introduce new technological ideas, but relied on old tactics and old maps for resources

the french commander, Joffre, believed that the spirit of the french soldiers would be done in the no mans land (full of barb wire)

the commanders on both sides believed that just using a large number of troops would make a breakthrough against machine guns and barb wire

the race to the sea

neither side could outflank each other

development of trench warfare being defensive rather than offensive

didn't want to loose ground

protection, many soldiers killed when the stood up
