Bertier continued to report on military affairs: "Regent Frederick guaranteed at least three ships of our 'goods' every week. The first batch of supplies should have arrived in Gdansk a few days ago, mainly military uniforms and gunpowder."
Joseph knew that among the three armies encircling Russia, only Poland was relatively strong, so France's support mainly targeted the Polish Army.
Considering that Prussia would surely not want to see Poland grow stronger, relying on them to transport supplies to Poland would likely encounter deliberate delays.
So he sought help from Denmark to mix military supplies with merchant ships headed for Gdansk. After Prussia's surrender, the "Gdańsk Corridor" was reopened, and thanks to its mature transportation system built over centuries, it could sustain Poland's logistics consumption.
