As the centenary of the end of the First World War approaches, Theresa May has used her speech to Conservative activists to pay tribute to those who died in the conflict.
The Prime Minister also highlighted the efforts to rebuild in the wake of the Second World War "where former enemies become friends".
"We remember the young men who left their homes to fight and die in the mud and horror of the trenches," said Mrs May.
"We remember the sailors who shovelled coal into hellfire furnaces in the bowels of battleships.
"We remember the selflessness of a remarkable generation whose legacy is the freedom we enjoy today."
The Prime Minister went on to say: "We must recapture that spirit of common purpose because the lesson of that remarkable generation is clear: if we come together there is no limit to what we can achieve.
"Our future is in our hands."
Mrs May also dedicated a section of her speech to the "national interest", saying she feels "most keenly" the responsibilities of her office when asking the military to put themselves in "harm's way".
The PM said she received "almost universal support" in Parliament to her response to the chemical attack by Russia in the UK.
