"Battle at Dam No. 4, Potomac River, between Butterfield's brigade and a large Confederate force. A desperate and disastrous action occurred on the banks of the Potomac, at Dam No. 4. General Butterfield's brigade, consisting of the Forty-fourth New York, Seventeenth New York, Eighteenth Massachusetts and One Hundred and Eighteenth Pennsylvania, were ordered to make a reconnoissance on the Virginia side. Crossing over at Dam No. 4, which is about six miles northwest in a straight line from Sharpsburg, and eight south from Williamsport, they had hardly landed when a most murderous fire was opened upon them from an entire division of the Confederate army, every volley of which told, as they had the Federals completely under range. The Federals made a desperate resistance, but they were compelled to retire before superior numbers, and retreated in moderate order across the river." —Leslie, 1896
