| quote       = Blocher’s Knoll had a distinct disadvantage. Though the swollen Rock Creek itself was a barrier of sorts, the trees along that stream as well as Blocher’s Run would give cover to advancing soldiers. Barlow sought to balance that by sending four companies of the 17th Connecticut across the bridge to the Josiah Benner homestead on the far side of Rock Creek. They were there as skirmishers to blunt the advance of Gordon’s troops and alert their comrades.

*'''Guinn Run'''  is a stream flowing southeastward from Cemetery Hill past the [[Gettysburg Museum and Visitor Center]] to Rock Creek.  The stream was bridged by the 1809 [[Gettysburg and Petersburg Turnpike Company]] and in the [[Gettysburg Battlefield#Commemorative era|commemorative era]] by the [[United States War Department]] when [[Hunt Avenue|Hunt]] and [[Slocum Avenue]]s were built.  A dam was built on Guinn Run to form a pond for [[Fantasyland, Pennsylvania]], through the 1960s and 1970s.[https://news.google.com/newspapers?id=HpEjAAAAIBAJ&sjid=eKMFAAAAIBAJ&pg=1396,3411367&dq=groundbreaking+cyclorama+gettysburg&hl=en]
