Did the American Riflemen get better at long range shooting as the war progressed? I think that likely, if not probable for the most part.
However, here is perhaps the most embarrassing account of the accuracy of Riflemen I have so far seen. The following is a combined synopsis of a fair number of accounts of the battle/skirmish.
It was at the Battle of Weitzel’s Mill in North Carolina on March 6, 1781. Part of the Patriot Army “Rear Guard” was under Col. Otho Holland Williams, who replaced Gen. Morgan after he took leave to recover from chronic rheumatism. Under Williams was Lt. Col Henry “Light Horse Harry” Lee and Lee’s Legion and some other Riflemen and Militia. Since Cornwallis was rapidly advancing, Col. Williams was trying to link up his forces with General Nathaniel Greene.
Part of the forces that were to cover the Army’s retreat and slow the British advance was a group of 25 Riflemen from Virginia, who were posted to help oppose/slow down the British advance across the Reedy Fork River/Creek on the South Bank. This while other Patriot forces were stationed to slow the British Advance in other nearby/supporting positions. At this point, there seems to have been a rather wide variety of accounts on the story.
Some accounts say that Light Horse Harry Lee ordered them in that position, while other sources say it was Col. Williams, the overall Commander. Lee may have ordered it from Williams’ direct order or may have chosen the spot for these riflemen, himself. Some accounts say the Riflemen were stationed behind a split rail fence while other accounts say they were in a good sized log building that had not yet been chinked. Whichever was the case, it seems the Riflemen had a good rest for their rifles to steady their aim. Accounts differ how far away the Riflemen were from the advancing British between 100 to no more than 150 yards away. What happened next is pretty much the same in all the accounts.
Cornwallis ordered British Lt. Col. James Webster to quickly advance and chase away the Rebel forces, so the rest of the British Army would not be under fire as they crossed. Some of Webster’s troops were reluctant to cross under fire, so Webster rode out ahead and slowly crossed the river/creek to inspire his own troops. Some accounts even mention Webster was a “portly fellowe.” (Maybe he did not know how to swim and rode slowly so as not to fall off and drown? However, this is only conjecture.) At that point, some accounts say Lee gave the order to fire on the British Lt. Col. Webster and other accounts say others did. What happened next is pretty much the same in all accounts.
As the “portly” Lt. Col. Webster was slowly crossing the stream, the group of 25 riflemen between 100 and 150 yards away, fired a total of 32 balls at him. Some accounts say it was a ragged volley with some of the men reloading and other accounts say the men fired individually. However, not a single ball touched that British Officer!! This group of Riflemen then quickly retreated.
32 balls fired at a single British Officer who was slowly crossing a stream and well within the Riflemen’s Range without a single shot hitting, did not say much for their accuracy that day. However, to be fair, they may have had the REST of the British Forces following the Portly Lt. Col. On their minds and worried what would happen to them after they fired.
