World War One represented a watershed in world history ,it was the first time that the industrial world utilised its weapons for mass destruction. The carnage that followed would have a profound effect on the rest of the 20th Century. The horrors of trench warfare and mass casualties had a massive psychological effect on everyone who was exposed it. Some tried to illustrate this through their poetry ,Wilfred Owen and Isaac Rosenberg both sought to expose the horrors through gritty realism, whilst others such Rupert Brooke concentrated on the world they were fighting for. All three poets paid the ultimate price losing their lives . As Wilfred Owen wrote “All the poet can do today is warn, that’s why the true poets must be truthful” The greatest epitaph to these three men was that they were true poets.
