By June 26 there were 7,671 ethnic Russians from Latvia's Latgale, representing ten percent of men from the region, serving in various units of the Latvian Legion. On July 1, 1944 the Latvian Legion had 87,550 men. Another 23,000 Latvians were serving as Wehrmacht "auxiliaries". The first Latvian Legion unit was the 2nd Latvian SS Brigade, created in February 1943. It fought its first battle in the Siege of Leningrad, opposite the Pulkovo observatory on 18 March 1943. It continued fighting around Leningrad until the German forces retreated in January 1944. The 15th Waffen-SS Division was formed and sent to the front in November 1943. Originally, it was sent to the Ostrov and Novosokolniki districts of Pskov Oblast, but after the German Army suffered setbacks there, was moved to positions in the Belebelka district of Novgorod Oblast in January 1944. It retreated from there a month later. At the end of February 1944, both units took joint defensive positions on the Sorota and Velikaya rivers. At that time, the 2nd Brigade was renamed the 19th Waffen-SS division. Over the next two months, these positions saw intense fighting. In April 1944, the Legion was replaced by other units and moved to less active positions in Bardovo-Kudever, 50 km east of Opochka. It came under attack there in June 1944 and started to retreat on July 10, 1944, crossing the Latvian-Russian border on July 17. In August and September 1944, the 15th Division was moved to Prussia, for replenishment with new recruits. It was in training near Danzig until being ordered into battle on 22 January 1945. At that time, the division consisted of about 15,000 soldiers. It fought near Danzig in January and February, retreating to Pomerania in early March. By early April, the division was reduced to 8,000 men. About 1,000 were sent by sea to replenish the forces in the Courland Pocket, the rest were lost during the fighting. On April 11, the division was told about plans to transfer the entire division to Courland. Seeing that the war was lost and understanding that being sent to Courland would mean eventually having to surrender to the Soviets, the division decided to surrender to the Western Allies instead, disobeying German orders to the contrary, when necessary.
