The gang got into a stolen Nash automobile that they had cleverly prepared by covering several numbers on the license plate with friction tape, just in case anyone saw them.
Bolly drove the car, and they arrived at the corner of Guilford and Genesee Streets about 9:45 A.M. Then they sat low and waited for the armored car to arrive.
The truck carrying the money had left Liberty Bank at Main and Court Streets about the same time they had arrived at Duffy and had the payroll for all three Duffy Silk Mill plants on the East Side.
By the time the armored car arrived it was about 10:00 A.M. It pulled into the driveway of the plant and drove into the yard, which was surrounded by a high steel fence.
As soon as the truck entered the yard, Korney yelled “Let's go!”
The six criminals exited the Nash and headed towards the yard, staying off to the side to avoid being seen by the guards. Ziggy and one of the others stayed at the gate to watch the street.
Meanwhile, armored car guard George W. McGee grabbed one of the three payroll bags containing $7,000 ($87,216) in his left hand, held his revolver in his right hand, and exited the truck.
Before he had a chance to see if it was clear, Bolly's revolver was in his face. “Drop the bag! Now!” Bolly demanded.
At the same time, the other three bandits were on the driver's side of the truck covering Albert W. Giese with their guns. Ziggy jumped on the truck.
“Hand over the revolver. Nice and slow,” Korney told Giese.
Bolly was at a standstill with McGee and was getting impatient very quickly. “I told you to drop the bag!” he ordered McGee once more, “or I'll fill ya full of lead!”
McGee handed the revolver to Bolly, and then the payroll bag. Bolly reached into the truck and tossed two more bags out, one to Korney and one to Smithy.
While Bolly held his revolver pointed towards the guards the bandits quickly backed out of the yard. When they reached the gate, they began to run. Ziggy and the other bandit kept their shotguns pointed at the armored car guards while the others ran to the stolen Nash.
