4. Union BATTERY 13 (1.7). The tour continues along Siege Road, passing the remains of this battery, which are to the left. The Union batteries were numbered consecutively, beginning with Battery 1 on the Appomattox River east of Petersburg and running south and west around the city. There were 42 of these Union batteries by the end of the campaign. In a like manner, the Confederate batteries were numbered starting at the river. In the original defense lines (the “Dimmock Line”) there were 55 Confederate batteries. Notice on the left of Siege Road, and at numerous other places throughout the tour, the low breastworks which connect the forts and batteries to make a long, continuous line. It was behind these that the enlisted men spent much of their time during the campaign. 5. FORT HASKELL (2.0), on the left of Siege Road, is one of the best preserved of the earthworks. The most important event in its history occurred on the morning of March 25, 1865, when the defense made here by Union troops helped turn the tide against the Confederates during the Battle of Fort Stedman. The moat, or ditch, around the embankments was made more formidable at that time with the aid of sharpened stakes (fraise) or brush (abatis). Chevaux-de-frise (timbers with sharpened stakes driven through at right angles) may also have been placed outside the moat. Gabions (cylindrical wicker baskets) and sandbags were placed on the fortifications to protect them from shot and shell. All of these devices were used regularly by both armies. Siege Road crosses the Union siege line a short distance beyond Fort Haskell so that the earthworks are now on the right (east) of you. The road leads through a ravine. 6. BATTERY 11 (2.3) is situated at the top of the rise from the ravine. This, along with BATTERY 12 (since destroyed), was captured by the Confederates in the Battle of Fort Stedman, March 25, 1865. In the course of the engagement that followed, the battery changed hands several times. After the final Southern withdrawal that same day, the battery remained in Northern possession until the end of the war.
