The presence of Saxon troops in the vicinity of Riga becomes more apparent in Dahlbergh's correspondence when 1699 becomes 1700. On 29 January he wrote to De la Gardie in Reval, informing him that rumours were saying that the Saxons had been transferred to the King of Denmark, i.e. would be used for some kind of diversion after a Danish attack on the Duke of Holstein. There was not much cavalry in Livonia, Dahlbergh wrote, but the small force available had been sent to the shores of the Daugava. Dahlbergh would be much obliged if de la la Gardie put the cavalry companies in Estonia on alert.
Two days later Dahlbergh sent a long report to Charles XII. There were no firm information yet, he wrote. One set of rumours suggested that the Saxons had been given to the King of Denmark and would be picked up by Danish ships for use in Holstein. However, Dahlbergh believed that this could well be an attempt to convince him that there was no danger to Riga. As the fortress Dünamünde was very weak he had sent an additional 360 men with 8 guns in order to discourage the Saxons, but as he did not dare to weaken the garrison at Riga Dahlbergh had ordered them to sneak back the same evening. Dahlbergh also told the King that a merchant in Riga had received word from Lithuania that Hetman Sapieha had told his people to abstain from transporting goods to Riga. The Governor General also pointed out that he had on two occasions appealed for the strengthening of Riga's defences.
The actions by Dahlbergh are also traceable in the orders he sent to various commanders. On the 27th of January he wrote to Major Haij at Kokenhusen, telling him to keep his eyes open. To von Ceumern, the leaseholder of Bersohn and Lubahn, Dahlbergh wrote that he was grateful for the information received, i.e. that once the Saxon troops advanced the local peasants would stop obeying the Swedes. Dahlbergh would be very grateful if Ceumern could obtain accurate information about the Saxons. On the 29th Dahlbergh wrote to Col. Skytte in Dorpat, telling him that Saxon units were gathering near the border, but it was still unclear what their intentions were.
