The Germans could take Memel and its hinterland, but that did not mean the Lithuanians would accept the loss. When the German invasion of Poland sparked the immediate French offensive promised by the Franco-Polish alliance, the Germans faced two active fronts at once. When they quickly pulled their mobile formations out of Poland to turn back the French invasion of the Saar, and the Lithuanians took advantage of their distress to recover Klaipeda/Memel.

Lithuania's good military performance in March bred overconfidence, and the troops that had stood their ground defensively were much less successful when attacking. The Germans held onto Memel, and Lithuania had reignited a war they could not hope to win. Their best hope now was for the French and Poles to win the war for them, and try to seize their lost lands when a better opportunity arose.
