The fight occurred in an alley between James and Norway streets shortly before 2 a.m., police said.
A 69-year-old James Street resident, who didn't want to be identified, said he called police after being awakened by noise from the alley.
He said that when he looked out his front door, he saw six or seven people yelling obscenities and swinging bats at each other.
"They started clubbing each other. It was terrible," said the man, who didn't get close enough to identify anyone in the fight.
Police said Saturday they don't know what may have provoked the fight.
Gormours was taken to Washington County Hospital, where he was in serious condition in the intensive care unit on Saturday.
A man with Gormours was also hurt when he was hit with a metal car jack, police said.
Mark Wayne Smith, 27, of 533 W. Church St., Hagerstown, had a bruised left leg but refused treatment, police said.
Both Knode and Sisler were charged with first-degree assault, second-degree assault and reckless endangerment on Gormours, police said.
In addition, Sisler was charged with second-degree assault and reckless endangerment on Smith, police said.
