Abatis, palisade and wire entanglement
The obstacle in front of the second parallel was carried westward by abatis across an arm of the marsh, then by inclined palisading, then by wire entanglement out to the booms across the creek. Brooks noted that the general commanding had given him more instructions about this obstacle than about all the rest of the work together. The same day the CSS Juno captured a Federal boat’s crew in the harbor.
