the Second Battle of Târgu Frumos, elements of the division, together with elements of the Großdeutschland, managed to halt an armoured assault by the Red Army. The assault, which in many aspects bore similarities to those of the later British Operation Goodwood, was carried out by approximately 500 tanks. In early July, the division was ordered to the area near Grodno in Poland, where it formed a part of SS-Obergruppenführer Herbert Gille's IV SS Panzer Corps, covering the approaches to Warsaw near the Modlin Fortress. After the Soviet Operation Bagration and the destruction of Army Group Centre the German lines had been pushed back over 480 kilometres, to the outskirts of the Polish capital. The division arrived at the Warsaw front in late July 1944. After the collapse of the German Army Group Centre, the IV SS Panzer Corps was one of the few functioning formations on the central section of the Eastern Front. On 1 August 1944, the Armia Krajowa (the Polish Home Army) launched the Warsaw Uprising. A column of Totenkopf Tiger tanks were caught up in the fighting, and several were lost. The Totenkopf itself was not involved in the suppression of the uprising, instead guarding the front lines, and fighting off several Red Army probe attacks into the city's eastern suburbs. In several battles near the town of Modlin in mid-August, the Totenkopf, fighting alongside the SS Division Wiking and the Hermann Göring Division destroyed the Soviet 3rd Tank Corps. The terrain around Modlin is excellent for armour, and Totenkopf's panzers exploited this to their advantage, engaging Soviet tanks from a range where the superiority of the German optics and the 75 mm high-velocity gun gave the Panthers an edge over the T-34s. Budapest relief attempts The efforts of the Totenkopf, "Wiking" and "Hermann Göring" divisions allowed the Germans to hold the Vistula line and establish Army Group Vistula. In December 1944, the IX SS Mountain Corps (Alpine Corps-Croatia) was encircled in Budapest. Hitler ordered the IV SS Panzer Corps to redeploy south to relieve the 95,000 Germans and Hungarians trapped in the city. The corps arrived just before New Year's Eve. The relief attempts were to be codenamed Operation Konrad. The first attack was Konrad I. The plan was for a joint attack by the Wiking and Totenkopf from the town of Tata attacking along the Bicske-Budapest line. The attack was launched on New Year's
