Our final stop on what was an incredibly long day was to the area where the May 18 battle of Harris Farm was fought. Much of it is now an upscale housing development and this monument to the 1st Massachusetts Heavy Artillery is smack dap in the middle of someone's front yard. Our apologies to the landowners, but Chris is from the same town in Massachusetts where most of this unit was organized and because he is leaving Antietam for Boston National Park this week, we figured we pay our respects before he left. . .
