On 25 July 1700 Vellingk was forced to inform Charles XII that the Saxons had been able to cross the Düna in force. In light of the General's previous optimistic assessments of the situation this must have embarrassed him. What had happened?
Well, according to Vellingk the cause was Governor General Dahlbergh's failure to keep the army supplied. Otto Vellingk had, he stated, repeatedly asked Dahlbergh for bread but none had arrived. Major General Maydell's advance party of 2,700 men had been without bread for three days and had been unable to remain. On the 20th Vellingk had anvanced towards the Saxons with his entire army, but they had already built a formidable camp near the shore. Vellingk placed his force in battle order, but could not get the Saxons to attack. Finally he had been forced to withdraw towards Yxkull. The Saxons pursued and as Vellingk considered them to be significantly stronger (about 14,000 to 15,000 men) than his own army (about 8,000), he decided to continue his withdrawal. During this two squadrons of the Åbo Cavalry were attacked, but the enemy pulled back when these were supported by infantry. The enemy had used a peculiar tactic. Each horseman was supported by a musketeer sitting beside him, who stepped forward and fired when the cavalry was about to attack. The Swedish cavalry withstood this fire as well as the fire from the Saxon horse and returned fire. A lot of Saxons were killed and 30 Saxons horses with empty saddles came over to Swedes.
In this situation Vellingk sent an officer to Dahlbergh, informing the Governor General that only two options remained. Either to fight the Saxons, in which case Dahlbergh ought to send 2,000 men from the Riga garrison or further retreat. Dahlbergh replied by sending Governor Frölich and colonels Wangersheim and Albedyhl, who informed Vellingk that no reinforcements from the garrison were possible. Instead Vellingk should detach 4,000 infantry from his own army as well as some cavalry. Vellingk accepted and kept only 1,600 infantry. Dahlbergh also took 400 cavalry. This meant, Vellingk wrote, that the garrison in Riga was stronger than the Saxon infantry.
Vellingk hoped that the events would not be harshly judged by the King. All the officers under his command had conducted themselves very well and he hoped that no one would be able spread unfavorable stories. He could have crossed the Düna himself, but too much was lacking. There was a shortage of fodder for the horses and the two Governor Generals had not been very helpful.
