 Here they set up camp and patiently waited since early June 1415 until the most of the army finally gathered, pouring down from Hungary proper and Slavonia and as far away as Germany, Bohemia, Lithuania, and Poland.Some of the units and weaponry were transported to the main Hungarian camp via boats, from river Sava down to river Bosna, which at that time flowed directly under the fortress (“...qualiter die XVI husus Johannes de Ghara cum multus gentibus scuritatis vestie appulerat in Uxora subtus castrum Dobuy qui ut fertur venit versus Bosnam”, Ragusan Council letter sent to Emperor Sigismund, dated June 28th 1415) .The actual battle took place around August 10th 1415 primarily in the area of Makljenovac, some 5 kilometers due south.
