One of the more interesting set of Forgotten Battles of the WWII Axis-Soviet War are the Battles of Narva in the spring to summer of 1944 IOTL. Here Army Group North repeatedly defeated various Soviet attacks aimed at the city, to a point that it fell relatively late in 1944, with all kinds of impacts on the outcome of the Soviet war machine in the northern sector. The challenge, should you choose to accept it, is to have the Soviet Leningrad Front capture Narva earlier than it did IOTL, as well as any realistic impacts this would have on the overall development of the 1944 Soviet offensives.
