"After the normalization of relations with the Holy Roman Empire and Bohemia, Mieszko I returned to his plans of conquest of the more western part of Pomerania. On 21 September 967 the Polish-Bohemian troops prevailed in the decisive battle against the Wolinians led by Wichmann the Younger, which gave Mieszko the control over the mouth of the Odra River.[28] The German margraves had not opposed Mieszko's activities in Pomerania, perhaps even supported them; the death of the rebellious Wichmann, who succumbed to his wounds soon after the battle, may have been in line with their interests. A telling incident took place after the battle, a testimony to Mieszko's high standing among the Empire's dignitaries, just one year after his baptism: Widukind of Corvey reported that the dying Wichmann asked Mieszko to hand over Wichmann's weapons to Emperor Otto I, to whom Wichmann was related. For Mieszko the victory had to be a satisfying experience, especially in light of his past defeats inflicted by Wichmann."

"Mieszko consolidated the work of his predecessors by strengthening Poland with a network of castle towns and fortified settlements. Expanded fortifications of wood and stone dating from the time of Mieszko have been unearthed by archeological excavations at sites such as Gniezno and Poznań. Under Mieszko the Polanie eventually gained control of Mazovia, Kujavia and Eastern (Gdańsk) Pomerania. When Mieszko and his son Bolesław undertook journeys around this enlarged territory, because of the great distances they sometimes stayed overnight in tents. For this reason they were accompanied, the chronicles tell us, by żerdźicy, or polemen, whose task was to erect the tents, to take them down, and to transport them. The term derives from żerdź, or pole (specifically, a sapling from which the branches have been removed).
Mieszko maintained a large, three thousand-strong, well-equipped personal force of professional soldiers, the drużyna, and a large army consisting of mounted and foot soldiers. Extensive trade at Wolin and Szczecin on the Baltic sea led Mieszko to annex Lubusz-land and Western Pomerania (with Szczecin) in 967. Here he came into conflict widi the Germans, the Volinians, Veletians and Raterians. The latter three were Slavs native of the area. To insure his conquest, Mieszko paid tribute to the Germans for this land on the Odra river and the Baltic sea. In return he received the appellation, Amicus Imperatoris."

Efter min opfattelse, som er dannet efter en del års interesse for Polen i 9., 10., og 11. århundrede, kan Mieszko i en periode have kontrolleret områderne ved Oders udmunding i Østersøen.
Men jeg vil gerne modbevises med relevante kildeangivelser.
