At the battle of Cowpens the American line was divided, in a brilliant plan by Brigadier General Daniel Morgan, into three lines. The first line were the skirmishers, and this photo is from their vantage point as the British advanced up the Green River Road. The militia sharpshooters were to fire twice and then retreat through the line behind them, manned by more militia, and reform with that line and fire once more. Then the whole second line was to retreat behind the third line, Howard's Continentals (who were not visible as the British approached by strategic placement behind a depression in the landscape) and protect the flanks of those troops. William Washington added another dimension to the plan with the addition of about 200 calvary troops.
