Red Army loses 40,000 men, 600 tanks
Thursday, March 18, 1943 www.onwar.com
On the Eastern Front... The German Army’s elite “Grossdeutchsland” Division attacks Belgorod in the finale to Manstein’s counteroffensive in the Kharkov area. The Soviets suffer 40,000 casualties and lose at least 600 tanks in this final encirclement operation. Manstein’s counteroffensive is widely considered an unqualified technical success that restores the German southern front after the debacle at Stalingrad. A large Soviet salient remains to the north, centered on the town of Kursk. However, the operational tempo declines over the next few weeks as the mud of the spring thaw limits mobility on both sides.
In Tunisia... The US 2nd Corps (commanded by General Patton) captures Gafsa and advances toward El Guettar.
In Burma... General Wingate leads the final gropu of Chindits across the Irrawaddy river, south of Inywa. The Japanese have assembled considerable forces to counter the Chindits operations. Meanwhile, in Arakan, Htizwe falls to a British pincer attack and an attack on Donbaik, on the Mayu Peninsula, fails.
