Qoraal sii-socda faqradan - Horraantii 1670-yadii, Frederick William wuxuu taageeray isku dayga Imperial ee dib u soo celinta Alsace iyo ka hortagga ballaarinta Louis XIV ee Faransiiska. Ciidamada Iswiidhan waxay soo galeen Brandenburg sanadkii 1674, halka inta badan ciidamada doorashada ay ku jireen jardiinooyinka jiilaalka ee Franconia. Sanadkii 1675 Frederick William ciidamadiisii waqooyiga ayay u soo mareen waxayna hareereeyeen ciidamadii Wrangel. Doorasho-doonka ayaa guushiisii ugu weyneyd ka gaadhay dagaalkii Fehrbellin
Inkastoo uu ahaa dagaal yar, wuxuu caan ku noqday ciidanka Brandenburg-Prussia wuxuuna Frederick William ku magacaabay "Great Elector". Kadib markii Sweden ay ku soo duushay Prussia dabayaaqadii 1678, ciidamada Frederick William waxay ka saari jireen soo duulayaasha Iswidishka intii lagu jiray "Great Sleigh Drive" ee 1678-79; Thomas Carlyle wuxuu isbarbar dhigay dib u dhaca Iswiidhishka ee xilliga qaboobaha ee Napoleon ee Moscow.
