MARYE’S HEIGHTS
McClellan was replaced as commander of the Army of the 
Potomac by  Major General Ambrose E.  Burnside. Once in 
the saddle,  Burnside  set  about  fulfilling  Lincoln’s  wish  for 
the  army  to  take  up  the  fight  with  Robert  E.  Lee’s  forces 
again. He finally engaged Lee at Marye’s Heights, just west of 
Fredericksburg, on December 13, 1862. 
Lee’s men had taken up fortified positions at the crest of 
a slope, with many in place behind a long, stone wall, 4 feet 
(1.2 m) high. Before the battle reached the Heights, Burn-
side’s main body of troops had to cross the Rappahannock, 
which  flowed  directly  past  the  town.  Efforts  to  lay  down 
a  pontoon  bridge  across  the  400-foot  (120-m)  wide  river 
turned nightmarish, as Federal engineers were picked off by 
Mississippi  sharpshooters  hidden  in  the  town’s  waterfront 
warehouses. Eventually, Burnside ordered his men into the 
pontoons to cross the river by boat.
On  the  morning  of  December  13,  Burnside  ordered  a 
direct  frontal  assault  against  Lee’s  75,000  well-entrenched 
defenders of Marye’s Heights. Although the Union men num-
bered 130,000, they could not match the Confederates, who 
occupied  the  high  ground.  Men  moved  forward  and  were 
cut  down  in  rows. Each  assault  ended  in  a  retreat.  In  all, 
Burnside ordered 14 charges up the hill in the face of Rebel 
guns. So many men were cut down that blue-clad soldiers 
lay on the field in stacks of two or three deep. 
A brigade of Irishmen moved up the hill, getting within 25 
paces of the wall, then riflemen of the 24th Georgia, nearly 
all of them Irishmen, too, shot them to pieces. From the top 
of the ridge above Marye’s Heights, Robert E. Lee observed 
the repeated assaults by Federal forces, only to watch them 
fall in great numbers. At one point, he noted, as historian 
Douglas Southall Freeman records, “It is well that war is so 
terrible—we should grow too fond of it!”
