From Azog's perspective. What was the strategic plan for the battle to attack the Lonely Mountain? -Azog leads the Dol Guldur vanguard in a rush to Lonely Mountain to contain the (potential) dwarven forces, while the main Gumbadar reinforcements outflank the enemy from the rear. Capture the Lonely Mountain in one fell swoop and open up the northern road. Alternative: Occupy the town of Riverdale and hold it for a long time.
Azog's strategic prediction for this war: there are only thirteen people in Sorin's squad. The refugees from Long Lake Town will inevitably head to Lone Mountain for help and hold Riverdale Town. Thorin (with great likelihood) will gather the Dwarven factions to come and recognize the legitimacy of his ascension to the throne. Thranduil (probably) will bring the forces of the Dense Forest to guard the garrison at the Lonely Mountain for negotiations. It should be mentioned here that as a viewer, God's perspective, it's easy to see that Thranduil and Thorin don't get along, but Azog he doesn't realize the depth of the water.
Azog's tactical objectives for the battle: Phase 1: march as fast as possible and attack the unsettled forces around the Lonely Mountain. Phase 2: Capture the town of Riverdale as a stronghold. Phase 3: To coordinate with the main force in the north to attack from behind. Once an order is given, it is very disruptive to change it during the war. Furthermore, Azog was the commander-in-chief, the leader of the vanguard, and a wolf scout in his own right in this battle. He was already on a wild goose chase from Dol Guldur, and the only information he could see at the front of the line was that "the refugees and elves from Long Lake were already stationed in Riverdale" and "Ironfoot had arrived with his troops to form up", so there was no way that he could have ridden a wolf through the forested army to listen to Thranduil and Dain bicker.
To put it bluntly, Azog is not a spectator without a God's perspective, he stood so high up on Raven's Ridge and saw a Miren army and a Dwarven army at his feet, how did he know whether these two armies were discussing how to fight the enemy together, or were preparing to engage in a firefight, or whether they were just showing off and maneuvering with each other? You stand on the Pearl of the Orient to see the two gangs below the fire fight before standing in line do not know also thought that the two teams in the square dance. He could only see two groups of dense armor highlights had not yet deployed defensive formations, and all he could do at the moment was to attack as fast as possible according to the predetermined plan. This is reasonable.
