"The Scotch-Irish settlers in the Valley of Virginia" - the Massacres of Kerr's Creek - Bolivar Christian, 1860

To help understand the experience of the early Ulster-Scots in the Shenandoah Valley of Virginia, this is a remarkable source - online here. There had been a number of massacres at Carr's Creek / Kerr's Creek, in 1759, 1763 and 1764. The writer says this:

"... When the captive survivors of the Carr's Creek massacre, in this (Rockbridge) county, reached the Shawnee towns on the banks of the Muskingum (Ohio), the Indians in cruel sport called on them to sing. 

Unappalled by the bloody scenes they had already witnessed, and the fearful tortures awaiting them, within that dark wilderness of forest where all hope of rescue seemed forbidden, undaunted by the fiendish revellings of their savage captors, they sang aloud with the most pious fervour from the 137th Psalm, as they oft had done in more hopeful days within the sacred walls of old "Timber Ridge Church":

"On Babel's streams we sat and wept when Zion we thought on,
In midst thereof we hanged our harps the willow trees among,
For then a song required they who did us captive bring,
Our spoilers called for mirth and said, a song of Zion sing."...
