Löwenberg slowly recovered during its reconstruction, but began to prosper again after its acquisition by the Kingdom of Prussia in 1741 during the Silesian Wars. Troops of the First French Empire occupied Löwenberg in May 1813, and Napoleon Bonaparte stayed in the town from August 21–23 while organizing his defenses against the Prussian troops of General Gebhard von Blücher. Following Macdonald's retreat after the Battle of the Katzbach with Blucher, General Puthod’s Division, including Vacherau's Brigade (The Irish Regiment, 134th &amp; 143rd Regiments), became isolated from the rest of the army. The River Bober (Bóbr) had risen out of its banks from the heavy rains and the bridges were under water. The division had been reduced to six thousand men and twelve pieces of artillery. On the morning of 29 August they reached the town of Lowenberg. It took up the best position it could find, on the narrow ridge above Plakowice, with its back to the river. All the bridges had been washed away and there was no possibility of constructing a bridge with the river flooding its banks on both sides. A combined Russian and Prussian Army of overwhelming superiority faced the Division but could only attack at the one narrow south-eastern end of the ridge. The battle began at 8:00 am and lasted until after 4:00pm. When the Division had expended the last of its ammunition, the enemy attacked and overran its position.
