A shell into the enemy’s works
One of Fort Moultrie’s shells fell into the Federal works on Morris Island and caused a great explosion, thought to be ammunition chests. Major Jenkins telegraphed from John’s Island that the enemy had bridged the creek and established a line of communication across the marsh from Dixon’s Island to Folly River. Confederate telegraph operators near Lowndes’ Mill on the Combahee were captured the same day.
