He says that the colonists have tried for a long time to talk to the British government and make their lives easier, but their pleas fell on deaf ears. This is why he says the following:
<span><em>If we wish to be free if we mean to preserve inviolate those inestimable privileges for which we have been so long contending if we mean not basely to abandon the noble struggle in which we have been so long engaged, and which we have pledged ourselves never to abandon until the glorious object of our contest shall be obtained, we must fight! I repeat it, sir, we must fight! An appeal to arms and to the God of Hosts is all that is left us!
</em></span><em />He ends his speech by stating his famous sentence - Give me liberty or give me death!
