this is not the time to leave any card unplayed. the impending presidential election in the north and the military stalemate in virginia meant that battles had to be one now or never. and these battles of the overland campaign are just remarkably bloody and costly to the north, and very costly to lincoln. we told you about what that is doing in the summer of 19 -- 1864, also undermine lincoln's political power. as soon as hunter retreated to they movedia, rapidly. for the reasons you heard, which washington and in order to put the political pressure on, and also to try and get grant to send them to washington, which he does. you can see that early expansion into maryland and pennsylvania seems to be not for any political -- military goal, because i do not believe, and i would be curious to hear in the discussion, if they believed they could actually take washington dc. i think he thinks he can shift the focus of attention to the continuing threat that the confederate army still poses after all of the sacrifice the north has made. so
