friendship eased the tensions between the Bavarian and Imperial armies. In October 1637, Enkevort returned to the Rhineland where the Imperialists and their Bavarian allies pushed Bernhard out of his last stronghold in Alsace. In early 1638, Bernhard launched an unexpected counter offensive, besieging Rheinfelden. Werth and Federico Savelli collected 2,600 infantry and 4,500 cavalry from the surrounding garrisons, rushing to relieve Rheinfelden. On 28 February, the advance of the Imperialists was blocked by Bernhard's cavalry pickets outside of Beuggen, they then headed towards the west in an attempt to deploy their forces in a more favorable position. The Bavarian cavalry which had reached Karsau ahead of the rest of the army, was attacked and thrown back. Savelli arrived with the infantry in time to support the Bavarians and force Bernhard to retreat towards Bad Säckingen. Lack of any sort of pursuit allowed Bernhard to regroup in Lauffenberg, upstream, where he received reinforcements from the other side of the Rhine. At 7:00 a.m. on 3 March, the Imperialist scouts became aware of the enemy presence at Lauffenberg. Before they were able to fully deploy, the Bernhardines fired a musket salvo at half range accompanied by cannon fire. The Imperial and Liga infantry was still reloading their muskets when the Bernhardines charged. The Imperial infantry broke formation, engaging in a disorganized retreat, so did the cavalry. Werth's elite infantry regiment was the only one to resist until it was surrounded and forced to surrender. The Battle of Rheinfelden was disastrous, Werth, Enkevort, general Sperreuter and Savelli were captured along with 3,000 of their men, while 500 were killed. Savelli escaped soon afterwards, after the woman tasked with bringing him food freed him instead. Enkevort spent the next three years in Paris, in relative comfort, even attending society events. Return from Captivity Enkevort was exchanged for a captured Swedish general in 1641, upon his return he was promoted to Generalfeldmarschall by Archduke Leopold Wilhelm of Austria. He then campaigned in Thuringia, between the areas of Aller and Leine. In the spring of 1642, he was transferred to the troops of Charles of Lorraine on the left side of the Rhine, although this front saw no major battles prompting his return to Bohemia. Under Leopold Wilhelm, he moved to Saxony, where the Imperial suffered a defeat at the hands of the Swedes in the Second Battle of Breitenfeld. In 1643, the new Imperial
