On 16 November 1918, the Estonian Provisional Government made the decision to create an armed force of volunteers. It was decided that army would consist of a single division which would have six infantry regiments, one cavalry regiment, one artillery regiment, and one engineering battalion. Major GeneralAleksander Tõnisson was assigned commander of the division, with ColonelJaan Rink as chief of staff. However, when the Estonian War of Independence started on 28 November 1918 with the Soviet attack on Narva, the Estonian Army numbered only 2,200 to 2,300 men, with the bulk of the fighting actually conducted by the paramilitary Defence League. Soviet forces included the 6th Red Rifle Division at Narva and the 2nd Novgorod Division south of Lake Peipus. After losing at Narva a period of retreat began for the 1st Division. Advancing against weak Estonian defences the Red Army captured Valga on 18 December, Tartu on 22 December, and Tapa on 24 December. In order to conduct a more flexible defence of South Estonia, a separate 2nd Division was formed on 24 December under command of Colonel Viktor Puskar. By the end of the year the Soviets had advanced to within of the capital, Tallinn. By the beginning of 1919 the Estonian Army had been increased to 13,000 men, with 5,700 on the front facing 8,000 Soviets. The strengthened Estonian Army stopped the 7th Red Army's advance on 2–5 January 1919, and went on the counter-offensive on 7 January. Tapa was liberated two days later with the support of armoured trains, followed by Rakvere on 12 January. With the aim of capturing Narva, a 1,000 strong Finnish-Estonian force was landed at Utria on 17 January, in the rear of the 6th Rifle Division, cutting off the Soviet forces west of them. On 18 January Narva was liberated. Subsequently, the northeastern front stabilized along the Narva river. Over the course of 11 days the 1st Division had advanced. After repulsing the Soviet forces in North Estonia the 1st Division was involved in active combat near Narva. During spring the Red Army made several unsuccessful attacks against 1st Division positions. By April 11,000 Estonians of the 1st Division were facing 16,000 Soviets near Narva, during which the main Soviet effort was concentrated in South Estonia. After the White Russian Northern Corps' offensive against Soviet forces began to fail in June at the hands of the 7th Red Army, the front was stabilized on Luga River and Saba River with support of the 1st Division. In July and August the 1st Division was involved in heavy fighting with Soviet forces in that area. At the end of September 1919, the Northwest Army had initiated a new attack on Petrograd, but was repelled by the Red Army in November. The 7th and 15th Soviet Armies advancing behind the collapsing White Russian forces continued to attack fortified positions along the Estonian border near Narva. The first clashes took place on the Luga River on 16 November, starting the final battles of war with 120,000 Soviets facing just 40,000 Estonians. After repeated attacks on the fortified Estonian positions, the 7th Red Army managed to achieve limited success. At the end of November the situation on front calmed as the Soviets needed to replenish their forces. In order to exert pressure on Estonia in the peace talks, intensive Soviet attacks resumed on 7 December. On 16 December there was critical breakthrough, with the 15th Soviet Army crossing the Narva River, however the Estonian counter-attack the following day successfully pushed the Soviets back. The Estonian high command actively reinforced the 1st Division at Narva during the fighting, dispatching the 3rd Division command, while general Tõnisson became commander of whole Viru Front. He was replaced as 1st Division commander by Colonel Otto Heinze. After suffering 35,000 casualties in the heavy battles, the Red Army was completely exhausted by the end of December. A ceasefire came into effect on 3 January 1920. Post war 1st Division staff was based in Rakvere. Since 1 February 1940, the division was made up by the Narva Military District and Viru-Järva Military District.
