Moller, born in 1690, joined the Prussian military on 26 January 1720 as a cannoneer in the artillery corps, of which his father was the regimental quartermaster.

[2] Although the Austrians held the higher ground as far as the infantry and cavalry were concerned, and the artillery thundered from the heights above the Prussian line so long and so loudly that even seasoned veterans became unnerved: some of the Croats in Maximilian Ulysses Reichsgraf von Browne's army fled to the rear of the field and even Browne himself, a life-long veteran, admitted to never hearing anything like it.

Frederick wrote to Field Marshal Kurt Christoph Graf von Schwerin: "Moller has done miracles and secunded me in an astonishing manner.

At about 3:00 pm, on the signal from Seydlitz himself, Moller's artillery opened fire on the Allied troops and tore huge gaps in their lines.

Soubise and his staff thought the Prussians were retreating, and using the guns as cover, and simply hurried to get out of range, but this further disorganized the Allied lines, and caused unit cohesion to break down.

Frederick's plan of attack was first to hammer the Russian right with heavy artillery fire and then to launch Heinrich von Manteuffel's advanced guard against it.

Moller opened fire with 60 total of his 18- and 24-pounders, placed in two locations around Zorndorf; the initial range was too far, so they closed about 600 paces, and then ripped the Russian squares apart.
