Battle of the Crater

During the Civil War, Petersburg, Virginia, was an important railhead, and four railroad lines from the south met before they continued to Richmond, Virginia, the capital of the Confederacy. Most supplies to Lee's army and Richmond funneled through there. Consequently, the Union regarded it as the "back door" to Richmond and as necessary for its defense.[5] The result was the Siege of Petersburg. It was actually trench warfare, rather than a true siege, as the armies were aligned along a series of fortified positions and trenches more than 20 miles (32 km) long, extending from the old Cold Harbor battlefield near Richmond to areas south of Petersburg.

After Lee stopped Grant's attempt to seize Petersburg on June 15, the battle settled into a stalemate. Grant had learned a hard lesson at Cold Harbor about attacking Lee in a fortified position and was chafing at the inactivity to which Lee's trenches and forts had confined him. Finally, Lt. Col. Henry Pleasants, commanding the 48th Pennsylvania Infantry of Maj. Gen. Ambrose E. Burnside's IX Corps, offered a novel proposal to break the impasse.

Pleasants, a mining engineer from Pennsylvania in civilian life, proposed digging a long mine shaft under the Confederate Army lines and planting explosive charges directly underneath a fort (Elliott's Salient) in the middle of the Confederate First Corps line. If successful, not only would all the defenders in the area be killed, but also a hole in the Confederate defenses would be opened. If enough Union troops filled the breach quickly enough and drove into the Confederate rear area, the Confederates would not be able to muster enough force to drive them out, and Petersburg might fall.

Burnside, whose reputation had suffered from his 1862 defeat at the Battle of Fredericksburg and his poor performance earlier that year at the Battle of Spotsylvania Court House, agreed to Pleasants's plan.

Digging began in late June, but even Grant and Meade saw the operation as a "mere way to keep the men occupied" and doubted it of any actual tactical value. They quickly lost interest, and Pleasants soon found himself with few materials for his project, and his men even had to forage for wood to support the structure.

Work progressed steadily, however. Earth was removed by hand and packed into improvised sledges made from cracker boxes fitted with handles, and the floor, wall, and ceiling of the mine were shored up with timbers from an abandoned wood mill and even from tearing down an old bridge.

The shaft was elevated as it moved toward the Confederate lines to make sure moisture did not clog up the mine, and fresh air was drawn in by an ingenious air-exchange mechanism near the entrance. A canvas partition isolated the miners' air supply from outside air and allowed miners to enter and exit the work area easily. The miners had constructed a vertical exhaust shaft located well behind Union lines. At the vertical shaft's base, a fire was kept continuously burning. A wooden duct ran the entire length of the tunnel and protruded into the outside air. The fire heated stale air inside of the tunnel, drawing it up the exhaust shaft and out of the mine by the chimney effect. The resulting vacuum then sucked fresh air in from the mine entrance via the wooden duct, which carried it down the length of the tunnel to the place in which the miners were working.[6] That avoided the need for additional ventilation shafts, which could have been observed by the enemy, and it also easily disguised the diggers' progress.

On July 17, the main shaft reached under the Confederate position. Rumors of a mine construction soon reached the Confederates, but Lee refused to believe or act upon them for two weeks before he commenced countermining attempts, which were sluggish and uncoordinated, and were unable to discover the mine. However, General John Pegram, whose batteries would be above the explosion, took the threat seriously enough to build a new line of trenches and artillery points behind his position as a precaution.

The mine was in a "T"-shape. The approach shaft was 511 feet (156 m) long, starting in a sunken area downhill and more than 50 feet (15 m) below the Confederate battery, making detection difficult. The tunnel entrance was narrow, about 3 feet (1 m) wide and 4.5 feet (1.4 m) high. At its end, a perpendicular gallery of 75 feet (23 m) extended in both directions. Grant and Meade suddenly decided to use the mine three days after it was completed after a failed attack known later as the First Battle of Deep Bottom. Union soldiers filled the mine with 320 kegs of gunpowder, totaling 8,000 pounds (3,600 kg). The explosives were approximately 20 feet (6 m) under the Confederate works, and the T-gap was packed shut with 11 feet (3 m) of earth in the side galleries. A further 32 feet (10 m) of packed earth in the main gallery to prevent the explosion blasting out the mouth of the mine. On July 28, the powder charges were armed.

The plan called for the mine to be detonated between 3:30 and 3:45 a.m. on the morning of July 30. Pleasants lit the fuse accordingly, but as with the rest of the mine's provisions, they had been given poor-quality fuses, which his men were forced to splice themselves. After more and more time passed and no explosion occurred (the impending dawn creating a threat to the men at the staging points, who were in view of the Confederate lines), two volunteers from the 48th Regiment (Lt. Jacob Douty and Sgt. Harry Reese) crawled into the tunnel. After discovering the fuse had burned out at a splice, they spliced on a length of new fuse and relit it.[9] Finally, at 4:44 a.m., the charges exploded in a massive shower of earth, men, and guns. A crater (still visible today) was created, 170 feet (52 m) long, 100 to 120 feet (30 to 37 m) wide, and at least 30 feet (9 m) deep.

The explosion immediately killed 278 Confederate soldiers of the 18th and 22nd South Carolina[10] and the stunned Confederate troops did not direct any significant rifle or artillery fire at the enemy for at least 15 minutes.[11] However, Ledlie's untrained division was not prepared for the explosion, and reports indicate they waited 10 minutes before leaving their own entrenchments. Footbridges were supposed to have been placed to allow them to cross their own trenches quickly. Because they were missing, however, the men had to climb into and out of their own trenches just to reach no-man's land.[12] Once they had wandered to the crater, instead of moving around it, as the black troops had been trained, they thought that it would make an excellent rifle pit in which to take cover. They therefore moved down into the crater itself, wasting valuable time while the Confederates, under Brig. Gen. William Mahone, gathered as many troops together as they could for a counterattack. In about an hour, they had formed up around the crater and began firing rifles and artillery down into it in what Mahone later described as a "turkey shoot."

The plan had failed, but Burnside, instead of cutting his losses, sent in Ferrero's men. Now faced with considerable flanking fire, they also went down into the crater, and for the next few hours, Mahone's soldiers, along with those of Maj. Gen. Bushrod Johnson and artillery, slaughtered the IX Corps as it attempted to escape from the crater. Some Union troops eventually advanced and flanked to the right beyond the crater to the earthworks and assaulted the Confederate lines, driving the Confederates back for several hours in hand-to-hand combat. Mahone's Confederates conducted a sweep out of a sunken gully area about 200 yards (180 m) from the right side of the Union advance. The charge reclaimed the earthworks and drove the Union force back towards the east.

Result of the 8,000-lbs. of powder explosion under the Salient, 1865

Union casualties were 3,798 (504 killed, 1,881 wounded, 1,413 missing or captured), Confederate 1,491 (361 killed, 727 wounded, 403 missing or captured). Many of the Union losses were suffered by Ferrero's division of the United States Colored Troops.[3] Both black and white wounded prisoners were taken to the Confederate hospital at Poplar Lawn, in Petersburg. Meade brought charges against Burnside, and a subsequent court of inquiry censured Burnside along with Brig. Gens. Ledlie, Ferrero, Orlando B. Willcox, and Col. Zenas R. Bliss. Burnside was never again assigned to duty. Although he was as responsible for the defeat as Burnside, Meade escaped immediate censure. However, in early 1865, the Congressional Joint Committee on the Conduct of the War exonerated Burnside and condemned Meade for changing the plan of attack, which did little good for Burnside, whose reputation had been ruined.[13] As for Mahone, the victory, won largely because of his efforts in supporting Johnson's stunned men, earned him a lasting reputation as one of the best young generals of Lee's army in the last years of the war.

Grant wrote to Chief of Staff Henry W. Halleck, "It was the saddest affair I have witnessed in this war."[14] He also stated to Halleck, "Such an opportunity for carrying fortifications I have never seen and do not expect again to have."[15]

Pleasants, who had no role in the battle itself, received praise for his idea and its execution. When he was appointed a brevet brigadier general on March 13, 1865, the citation made explicit mention of his role.

Grant subsequently gave in his evidence before the Committee on the Conduct of the War:

General Burnside wanted to put his colored division in front, and I believe if he had done so it would have been a success. Still I agreed with General Meade as to his objections to that plan. General Meade said that if we put the colored troops in front (we had only one division) and it should prove a failure, it would then be said and very properly, that we were shoving these people ahead to get killed because we did not care anything about them. But that could not be said if we put white troops in front."[16]

Despite the battle being a tactical Confederate victory, the strategic situation in the Eastern Theater remained unchanged. Both sides remained in their trenches, and the siege continued.

The Crater in 2004

The area of the Battle of the Crater is a frequently-visited portion of Petersburg National Battlefield Park. The mine entrance is open for inspection annually on the anniversary of the battle. There are sunken areas, where air shafts and cave-ins extend up to the "T" shape near the end. The park includes many other sites, primarily those that were a portion of the Union lines around Petersburg.

• The Battle of the Crater was graphically portrayed in the opening scenes of the 2003 film Cold Mountain, starring Jude Law as a Confederate soldier. The film inaccurately depicts the giant explosion occurring in broad daylight; it actually happened in darkness at 4:44 A.M.[17]
• The battle is also recounted in a historical novel, Battle of the Crater, by Newt Gingrich and William R. Forstchen.[18]
• The Battle Of The Crater, from Lambil & Raoul Cauvin, edited by Dupuis in 2019, is a Belgian comic book in the "Bluecoats"-series (Les Tuniques Bleues). The sixty-third comic book in the series tells how the leading characters, Corporal Blutch and Sergeant Chesterfield, participate in the Battle of Saint Petersburg. The album is fairly accurate in terms of historical facts and shows a few authentic details that took place during the battle.
