Explanation:

Patrick Henry in this excerpt from his 1775 speech to the Convention of Delegates in Virginia is imploring the delegates to open their eyes and see that Great Britain is fomenting war against the colonies and that in the text of the main speech he says for 10 years the colonies have been asking the British for better treatment and almost begging for it but all to no avail and so this is why he says that the idea of peace at all costs is wrong and that it is better to die fighting than be enslaved any longer by the British.
