From the Confederate journal of operations at Charleston for December 29, 1863:
About dark last evening [December 28], four large parties, supposed to be regiments of the enemy, were observed proceeding from Battery Wagner toward Cumming’s Point. It is thought the object of this movement was to repair the damages done to their works by the recent storm. General Ripley determined to interrupt their operations, and directed the batteries on Sullivan’s Island to open heavily, which they did at about 9 p.m. The commanding officer at Fort Johnson having been notified, the batteries adjacent to that work also joined in the action. About 45 mortar and 50 direct shells were thrown in half an hour, but the enemy did not reply. Our practice is said to have been fair, the chief defect being the oft-repeated one of fuses.
This may simply be a case of my laziness and not tracing down a specific account from the Federal side to this incident. Ninety-five heavy caliber shells rained down and not even so much as passing reference in a regimental history. Had that occurred anywhere but Charleston, the Official Records would have five to ten pages of reports. But on Morris Island, that was just another minor little bombardment. The sort of thing happening on any given day.
