As Bagramyan pushed towards Vitebsk, his forces were aided by the same Belorussian guerrilla fighters who had escaped the German encirclement in April. They provided vital intelligence, including information on the location of bridges and troop movements, and launched attacks against German logistic lines. On 22 June 1944, "Bagration" began as Bagramyan proceeded in moving westwards as previously planned. However, a widening gap on the Front's northern flank grew as it advanced while the Second Baltic Front, tasked to help defend that area, took no action. Stalin agreed to send a tank corps to reinforce Bagramyan's forces but ordered him to capture Polotsk, which would sever Army Group North's communication lines and open up a route towards the central Baltic. By 3 July, his troops had accomplished the tasks set forth in the directive, destroyed the Third Panzer Army and captured Polotsk. For his achievements, on 7 July he was decorated with the title of Hero of the Soviet Union.
