i think there is a misunderstanding on what a tactical victory is it does not mean a victory of tactical formation but rather a success in battle without substantive or long lasting gain as opposed to a strategic victory which is a success in a military campaign if one sets ones sights low enough and claim the goal of the operation was merely to establish a bridgehead then it was a clear soviet victory however i seriously doubt the goal was only to gain a bridgehead but rather to punch through the panther line which the soviets clearly failed to do while the overall campaign was a clear strategic victory for the soviets because they won the campaign in the end it was a tactical victory for the germans because they were successful in holding narva even though it was not long lasting i e six months
