MOSCOW--German tank and infantry charges broke up against staunch Red Army barricades in the streets of Stalingrad yesterday, but Axis forces striking down the Black Sea coast of the north-west Cancasus overran two inhabited localities, a Soviet communique said today.

Especially bitter fighting developed in one area of the North Stalingrad factory area as the great battle for that industrial region raged through its sixth day of climactic fury, the High Command's Monday midnight report said.

After acknowledging the loss of one city block in Stalingrad, 12 hours earlier, the High Command said all German attacks in the metropolitan area were countered successfully during the day.
