The Battle of Rain /ˈraɪn/, also called Battle of the River Lech, took place on 15 April 1632 near Rain in Bavaria during the Thirty Years' War. It was fought by a Swedish-German army under Gustavus Adolphus of Sweden, and a Catholic League force led by Johann Tserclaes, Count of Tilly. The battle resulted in a Swedish victory, while Tilly was severely wounded and later died of his injuries.

Outnumbered and with many inexperienced troops, Tilly built defensive works along the River Lech, centred on the town of Rain, hoping to delay Gustavus long enough for Imperial reinforcements under Albrecht von Wallenstein to reach him. On 14 April, the Swedes bombarded the defences with artillery, then crossed the river the next day, inflicting nearly 3,000 casualties, including Tilly. On 16th, Maximilian of Bavaria ordered a retreat, abandoning his supplies and guns.

Despite this victory, the Swedes had been drawn away from their bases in Northern Germany and when Maximilian linked up with Wallenstein found themselves besieged in Nuremberg. This led to the largest battle of the war on 3 September, when an assault on the Imperial camp outside the town was bloodily repulsed.

Swedish intervention in the Thirty Years' War began in June 1630 when nearly 18,000 troops under Gustavus Adolphus landed in the Duchy of Pomerania. Backed by French subsidies and supported by Saxony and Brandenburg-Prussia, victory at Breitenfeld in September 1631 gave him control of large parts of north and central Germany. This marked the highpoint of Swedish success; a Saxon army under Elector John George invaded Habsburg lands in Bohemia, Gustavus prepared to attack Austria, while his subordinate Gustav Horn advanced into Franconia.

In February 1632, Horn attacked the Bavarian town of Bamberg with a force largely composed of German recruits; Tilly marched north from Nördlingen with 22,000 men and on 9 March recaptured the town. Although he was too weak to follow up this success and withdrew to Ingolstadt, which controlled a major bridge over the Danube, Gustavus feared the effect this defeat might have on his German allies. Telling Horn "we must not let the enemy get any courage whatever against us", he abandoned plans to invade Austria and instead moved south into Bavaria from his winter quarters in Mainz. By consolidating his own forces with those of Horn, Johan Banér and Wilhelm of Saxe-Weimar, he assembled 37,505 men and 72 guns.

The Swedes entered Nuremberg on 31 March, then captured Donauwörth on 6 April, near where Tilly had established a defensive line along the River Lech. His main force of 22,000 was entrenched around Rain, with a detachment of 5,000 covering another crossing at Augsburg (see Map). Although Tilly accepted that Gustavus could outflank him by passing south of Augsburg, his objective was to provide time for the main Imperial army under Albrecht von Wallenstein to reach him.

At this point, the Lech river divided into a number of parallel, fast flowing streams, each about 60 to 80 metres wide; the bridge at Rain had been destroyed by Tilly, who placed his inexperienced troops in a strong redoubt with 20 guns, making it a formidable challenge for an attacker. The only other practical route was about five kilometres south of Rain, where there was an island in the middle of the Lech; a deep channel separated it from the Swedish side but it was possible to walk across to the Bavarian bank. Bridging this obstacle has been seen as one of Gustavus' greatest military achievements.

During 13 April, Lennart Torstensson supervised the construction of Swedish artillery positions opposite Rain, creating three separate batteries of 24 guns each. The next day, he opened fire on Tilly's redoubt while Gustavus deployed his troops near the river bank, making it seem he intended an assault. However, this was only a feint, intended to distract their opponents while they gathered boats and materials to build a pontoon bridge over to the island. On the morning of 15th, three hundred Finnish Hakkapeliitta troops crossed across to the Bavarian side; having done so, they then dug earthworks for batteries which protected the rest of Gustavus' army as they crossed the river.

Tilly immediately despatched troops to engage the Swedes and a fierce firefight developed as they tried to push them back; however, Gustavus had sent 2,000 cavalry over the river two kilometres north of Rain who circled round the redoubt and took them in the flank. Tilly's right thigh was shattered early in the battle; he was taken unconscious to the rear and died two weeks later, while his second in command, Johann von Aldringen, was temporarily blinded minutes later. Maximilian of Bavaria now assumed command and ordered an immediate retreat, covered by his cavalry under Scharffenstein. Both sides suffered around 2,000 casualties each, with the Swedes capturing another 1,000; although Maximilian was forced to abandon his baggage and artillery, most of his army escaped, helped by a storm and high winds which blocked roads and delayed pursuit.

Aftermath

Maximilian reinforced his garrison at Ingolstadt, which repulsed a Swedish attack on 3 May, then withdrew north of the Danube, leaving Bavaria open to the Swedish army. The country was extensively pillaged, while Gustavus made a triumphal entry into Munich on 17 May, confiscating the ducal art collection and capturing over 100 pieces of artillery; it was another three years before Maximilian re-entered his capital. On the other hand, the Swedes were now at the end of long and extremely vulnerable supply lines, while Bavarian peasants waged a bitter guerrilla war in the countryside against the invaders plundering their lands.

Meanwhile Wallenstein raised an Imperial army of 65,000, which he used to expel the Saxons from Bohemia; concerned Saxony might make a separate peace and leave him isolated, Gustavus now summoned his German allies to Nuremberg. As he did so, Wallenstein took 30,000 troops and marched into Bavaria to link up with Maximilian advancing north from Ingoldstadt and on 11 July the two forces met up at Schwabach (see Map above). Gustavus retreated to Fürth just outside Nuremberg where he was besieged by the combined Imperial-Bavarian army, leading to the Battle of the Alte Veste in early September.
