Answer:
The speech was given to Inspire the British to keep fighting
Explanation: In this speech he offers up everything ( his blood, toil sweat and tears) to have victory by any means necessary. He gave this speech to remind the British that hope was not gone. That they still had a reason to fight for and, that it was worth the battle. Since the Britsh felt it was impossible to win, This really helped to motivate them again.
Hope it helped :)
