Longstreet's Silent Charge at Gettysburg-- Part 1

From the March 20, 2019, Washington Post  "Weird weather saved America three times" by Gillian Brockell.

In June 1863 Confederate General Lee headed North, hoping a decisive battle might get the peace he wanted for his country.  Confederate General James Longstreet was with him and widely blamed for Lee's failure due to his lethargy of action.

But, according to one  theory, a bizarre phenomenon occurred known as an "acoustic shadow" may have played a role in the eventual Confederate defeat.

Lee ordered Longstreet to attack the virtually empty Little Round Top.  General Ewell's troops was to make a show of force at the other end of the Confederate lines to draw Union attention away from Longstreet. Ewell was to begin his action at the sound of Longstreet's artillery.
