Porphyrogenitus, Croatia at the time was able to field an army of 100,000 foot soldiers, 60,000 horse soldiers, 80 big battleships and 100 smaller battleships, but these numbers are generally taken as a considerable exaggeration. According to the palaeographic analysis of the original manuscript of DAI, the estimation of the number of inhabitants in medieval Croatia between 440 and 880 thousand people, and military numbers of Franks and Byzantines - the Croatian military force was most probably composed of 20,000-100,000 infantrymen, and 3,000-24,000 horsemen organized in 60 allagions. The Bulgarians were met by a Croatian army in the mountainous area of Eastern Bosnia. The Croatian forces completely destroyed the Bulgarians. Arguably key to the overwhelming victory was the choice of terrain on which the battle took place. Bulgarians at the time when the battle started were in an unfavorable position and the Croatian army had made a surprise attack against them. Croatian soldiers would probably have been more experienced in fighting in the mountainous terrain of the Bosnian highlands. The Croats adjusted their military tactics, time and place of the battle to their opponents who possibly outnumbered them, which brought themselves a decisive advantage. Duke Alogobotur most likely perished in the battle along with most of his soldiers since he is no longer mentioned in sources. Aftermath Simeon suffered a crushing defeat, but did not lose the bulk of his forces. He had sent a part of his army on that campaign and those forces had suffered heavy losses, but his overall army was strong enough to carry out another invasion of Byzantium. The Croatian-Bulgarian war did not continue in a significant extent, no territorial changes followed, and peace was concluded after the death of Emperor Simeon in 927. In 927 Pope John X sent his legates with Bishop Madalbert to mediate between Croats and Bulgarians. Simeon died in May 927. His son and successor Peter I renewed the war with the Byzantines and concluded a peace treaty the same year. Byzantine sources, specifically George Kedrenos, say that the cause for Peter's peace treaty proposal was his fear that all his neighbors, the Hungarians, Croats, Serbs and other, could take the advantage of Simeon's death to attack Bulgaria. In addition, Bulgaria had a major domestic problem, a severe famine resulting from an attack by locusts.
