Yesterday enemy troops pursued an offensive in the direction of Vilna and Baranovichi [White Russia]. In the course of the day sizeable Soviet aerial forces attacked the enemy units. Nevertheless a number of enemy armoured swarms succeeded in penetrating the Vilna and Oshmyany [White Russia] area. Thanks to the bitter resistance of our troops, enemy infantry units have been cut off from their armoured spearheads.

...after two days of fighting the German panzer arm brought to a victorious end a massive armoured battle north of Kovno in which a number of Soviet divisions were encircled and destroyed. We captured more than 200 Soviet armoured cars, 29 of them of the heaviest type, over 150 heavy guns and hundreds of trucks.

Our armoured units and motorised divisions have pressed along both sides of the Bialystock troop pocket and reached the area around Minsk. We are about to achieve another great victory.

ROMANIA: Major units of the Soviet Black Sea Fleet, including the cruiser VOROSHILOV and flotilla leaders (i.e. large destroyers) MOSKVA and KHARKOV, are repulsed in their attack upon the Romanian seaport of Constanta by accurate shellfire of the Royal Romanian Navy's coastal defence batteries (Gruparea de artilerie de coasta Constanta, comprised of six batteries ranging in size from 150mm and 120mm down to 75mm), in conjunction with fire from two Romanian naval destroyers (the Regina Maria and Marasti) along with the recently installed 28cm German coastal battery "Tirpitz."  Actual hits scored by defending batteries were, few in number, and the only probable hit being on the Moskva was actually credited to either Regina Maria or Marasti -- still, the Moskva was sunk as a result of this damage, with the added assistance of a mine which she struck while withdrawing from the action.

Maj-Gen Evetts (GOC 6 Brit Div) will command from Merdjayoun to Damascus. On the coast the Royal Navy shells French positions daily, particularly artillery positions at Abey. Nevertheless, the French artillery maintains a vigorous fire on the Australian infantry, firing concentrations of up to 200 shells at a time. Brig Plant pulls 21 Aust Bde back so as not to present an arty target, but orders vigorous patrolling in preparation for the Australian offensive to begin on 5 July. (Michael Alexander)

U.S.A.: In the final game of a three game series at Yankee Stadium in New York City, the St. Louis Browns send Elden Auker to the mound to face the Yankee's Marius Russo. As Russo later put it, "I was pitching a no-hitter into the seventh inning, but nobody cared. They cared only for one thing, to see Joe (DiMaggio) get a hit." And the hit came about thanks to some crafty managing by Yankee manager Joe McCarthy. 

The Yankees were leading the Browns 3-1, but Auker was giving DiMaggio trouble again. DiMaggio was 0-for-3, and because he was scheduled to bat fourth in the bottom of the eighth inning, there was a chance he might not get a last crack at Auker. Yankee first baseman Johnny Sturm opened the eighth inning by popping out, then third baseman Red Rolfe walked and here, McCarthy made sure DiMaggio got his at-bat. He instructed the powerful right fielder Tommy Henrich - who would hit 31 homers in 1941 - to bunt, therefore avoiding a possible inning-ending double play. Henrich sacrificed successfully, and up came DiMaggio. On the first pitch, he lined a double over third base. DiMaggio's hitting streak was now 38 games.
