In early 1945, Bagramyan's army, under the overall command of Vasilievsky, took part in the advance into East Prussia. In Operation Samland, Bagramyan's First Baltic Front, now known as the Samland Group, captured Königsberg (now Kaliningrad) in April. On 9 May 1945, he accepted the surrender of the German forces penned up in Latvia, capturing a total of 158 aircraft, 18,000 vehicles, 500 tanks and assault guns among other weaponry.
