Cause

King Henry the Fowler launched a broad eastern frontier campaign in early 929, targeting a series of Slavic strongholds following the capture of Brandenburg. The Glomacze fortress at Gana, situated near the Jahna river in what is now Hof/Stauchitz, was selected as the second major objective in this systematic effort to seize and consolidate territory along the German-Slavic borderlands.

Event

Henry's German army besieged the Glomacze fortress of Gana for twenty days, expending at least 110,000 man-hours in filling part of its protective ditch to overcome its defenses. Upon capturing the fort, Henry ordered the execution of the garrison, while the young boys and girls taken were enslaved by his professional soldiers, the milites.

Consequence

Following the fall of Gana, the Germans established a fort at Meissen, securing lasting dominance along the middle Elbe. The conquests of the 929 campaign were subsequently organized under the Marca Geronis, a new administrative march, illustrating the German kingdom's ability to annex and govern newly conquered Slavic territories.
