In April 1945, s.Pz.Jäg.Abt.512 saw a great deal of action, especially on 9 April, where the 1st Company engaged an Allied column of Sherman tanks and trucks from hull-down positions and destroyed 11 tanks and over 30 unarmored or lightly armored targets, with some of the enemy tanks having been knocked out from a distance of more than 4,000 m. The combat unit only lost one "Jagdtiger" in this incident as Allied ground-attack P-47 fighters appeared. During the next couple of days, the 1st Company destroyed a further five Sherman tanks before having to surrender to US troops at Iserlohn. Meanwhile, the 2nd Company still fought on but with little results gained. On 15 April 1945, the unit surrendered at Schillerplatz in Iserlohn without continuing fighting.
