Pic 1 shows two fragments of 6.4” shells. The fragment on the left is a typical example from Fort Fisher. The fragment on the right however has a severely off center shell cavity which resulted in a great discrepancy in shell wall thickness. I assume this shell was very unstable in flight.
Pic 2 shows the fragments stacked for additional perspective.
I eyeballed the “off center” fragment back in the late 1970’s when roads were cut through Redoubt (Fort) Dutton on the Bermuda Hundred Line. I assume the fragment is from a Confederate shell but I honestly do not know who or where it was fired from. Dutton is a long way from either the James or Appomattox rivers and I did not think the Battery Dantzler’s big guns could traverse that far inland.
