As Rostislav made his decision, the entire military camp sprang into action.
First, soldiers skilled in water were secretly assembled; these individuals would swim north to the sandbars first, where they would establish some crude fortifications using the wooden stakes they brought and the stones from the sandbars.
Moreover, on the western cliff, the German Engineer-led sapper battalion was setting up the ballistas they had brought.
The purpose of these ballistas was to watch out for any potential Bulgar warships and to provide some fire support for the Ross Army's river crossing.
And next to these ballista positions were the archers' firing positions, who would provide cover for the advancing troops.
Various boats of the Ross forces were also gathered and began to construct a pontoon bridge.
The teams building the pontoon bridge were patrolled by large and small boats, all laden with archers.
As for the various armies, they were mobilized, assembling in the designated river crossing areas, ready to cross the river at any moment.
As the busy army unfolded, everyone realized that Rostislav was truly going to act, not just feint—Rostislav had organized several fake landings in the past.
Such a large movement was naturally noticed by the Bulgars on the opposite side, and the Ross people had no intention of hiding it from them, as it was impossible to conceal.
After the Ross people arrived at the Kama River, the Bulgar army also gathered there, and now they began to consciously move towards the sandbar area.
On this night, when battle was to unfold tomorrow, everyone was doing different things to pass the time before the war.
Some wanted to leave their seed before the battle, so they spent the entire night planting with prostitutes, while others were silently sharpening their weapons and maintaining their armor to cope with tomorrow's fight.
But more people were sleeping soundly; they didn't have so many thoughts in their minds, figuring that whatever happened in the future, they would deal with it then.
The soldiers below could do all sorts of things, but the commanders of the two armies could not; Rostislav and his generals were waiting together.
At the same time, they continuously organized the information from the scouts and adjusted the troop allocation based on new intelligence.
The Kama River was not peaceful at the moment; at every moment, scouts from both sides were trying to sneak across to ascertain the movements of the opposition.
Naturally, there were many skirmishes during such infiltrations, and there were even instances where two waves of scouts ran into each other and fought; there was never a shortage of fighting in the dark of night.
Sometimes the scale of the battles would even expand, with the warships of both sides shooting at each other on the Kama River, but such battles were quickly called off by the tacit understanding of the commanders on both sides.
Now was not the time for a decisive battle; now was the time to preserve strength for tomorrow's fight—this was the tacit unwritten rule between both sides.
While the Ross commander was enduring, on the opposite side, the Bulgar commander was also enduring.
Akad Mosk Turuk, the one people called the Kinslayer, the usurper Khan of the Bulgar Khanate, was now sitting alone in his tent.
Akad's tent was very luxurious and conspicuous among the ordinary tents, but this was not due to his desires, but because Akad needed the soldiers to be able to see him at all times.
Akad's army relied entirely on his personal prestige; without him, this force, mixed with religious figures, foreigners, and Bulgar lords, would directly fall apart, and his son did not have the ability to command these people.
Akad's time had been very precarious, but he had managed to get through it and stabilize the situation.
And the one thing he had been doing during this time was bringing Suvar under his control.
Akad had always been aware of Suvar's betrayal; he understood the city's intentions perfectly.
If there was an opportunity to pull down Bulgar's dominant position, they would not let it pass.
After Suvar sheltered those who dared to resist him, Akad confirmed their betrayal, so he devised a plan.
Just a week ago, Suvar suddenly found a large number of refugees and believers pouring into their city.
At that time, Akad announced that he would cross the Kama River to attack, coupled with the fighting on the west bank, so the appearance of these refugees did not surprise them much.
As for the believers, Suvar was after all the second largest city in the Bulgar state, and its mosques would naturally attract many pilgrims; coupled with the impact of the war, Suvar did not find anything strange.
But it was these unstrange occurrences that led to the city's loss of autonomy.
First, the refugees rioted due to insufficient food, and then the believers claimed that Suvar was betraying Allah, so the scope of the riots grew larger and larger.
And it was when Suvar was busy dealing with the internal rebellion that Akad's army, which he had said would cross the Kama River, appeared at the city walls, and then the rioters inside the city opened the gates.
After the city gates were opened, Akad's army entered the city, swiftly taking control of various key points.
As for Suvar's citizen militia, they couldn't even assemble, and the small standing army was immediately annihilated.
Next, Akad began a counter-reckoning within the city, arresting all the opposition figures sheltered by Suvar.
He did not kill these people, but brought them here to serve as catapult ammunition, sending this group to meet his nephew.
Suvar's nobles and wealthy families were all confiscated and exiled by him.
The wealth gained allowed Akad to draw more fence-sitting Bulgar lords into his army, and his army, filled with foreigners and mercenaries, quieted down.
It can be said that the power of the city of Suvar was thus dismantled.
To ensure foolproofness, Akad also moved a large number of his own people into the city, letting them take over the properties of those who had been exiled.
All of this was achieved within a week, and the cost of achieving this result was that the Ross people completely gained control of the Bulgar territory west of the Kama River.
This at one point caused considerable impact on his authority, but the use of the butcher's knife quickly stabilized the situation.
Moreover, from the very beginning, Akad had this idea.
He knew that the Ross people were powerful, their army difficult to deal with, and their numbers far greater than his, so he had to find other advantages to offset the Ross people's strengths.
Therefore, he set the battlefield on the Kama River, a city that the Bulgars had controlled for countless years.
Here, he had prepared many surprises for the Ross people, and he was also ready for a tough battle.
