oenders. Arrests were made in relatively modest numbers in other states be-
cause of Klan inactivity or the unwillingness of federal and state authorities to 
detain Klan suspects for fear of provoking more insurgent violence.58
e prosecutions of July and August failed to intimidate the insurgents 
in much of the South, for Klan outrages continued on a large scale, especially 
in South Carolina. Brigadier General Alfred Howe Terry, commander of the 
Department of the South, told Grant in late August that the army ought to 
crush the Klan decisively in one place, South Carolina, to discourage Klans-
men elsewhere. Because the army’s presence in the South was so small—only 
8,038 regulars were on occupation duty in 1871—it was impossible to attack 
the insurgents in many states at once.59
e reports from South Carolina in late August so worried Grant that he 
le Long Branch and sent the U.S. attorney general, Amos T. Akerman, to visit 
the Carolinas to see what was going on. Akerman reported back that the presi-
dent should use everything at his disposal, including suspension of habeas 
corpus, to strike at the Klan. On October 17, Grant suspended habeas corpus 
in nine South Carolina counties, the rst time the writ had been suspended 
in peacetime, and the U.S. marshals and federal troops began mass arrests. 
As the federal government cracked down, the insurgents oered little armed 
resistance, opting instead to lie low or ee the state.
e most eective Union commander in the South Carolina campaign 
was Major Lewis Merrill, who was assigned to York County, in the Piedmont 
area bordering North Carolina. Merrill had attended West Point, where he was 
an unexceptional performer, graduating twentieth of the thirty-four students 
in the class of 1855, and a serious troublemaker, having nearly been court-
martialed for threatening an instructor. A tall man of athletic build and elegant 
bearing, Merrill exuded charisma. In 1861 and 1862 he led Union cavalrymen 
in hunting down secessionist guerrillas in Missouri, showing little mercy to 
the enemy. Aer he executed twenty-two captured guerrillas by ring squad, 
he became so controversial a gure that President Lincoln summoned him 
to the White House for an explanation. Merrill described to the president the 
murders these men had committed, and said that he had tried unsuccessfully 
to obtain approval from Washington for the executions. Lincoln put his hand 
on Merrill’s shoulder and said, “Remember, young man, there are some things 
which should be done which it would not do for superiors to order done.” 
Merrill went on to participate in the capture of Little Rock in 1863. During his 
service in Missouri and Arkansas, he demonstrated a variety of talents, most
