Further reading shows that the 28th Squadron occupied Lambertsberg on March 1st:
"Despite strong enemy resistance, the VIII Corps under Patton’s Third Army advanced along both sides of the Prüm River. To protect the left flank of the 87th Infantry Division, the 11th Armored Division’s Combat Command A was attached to the 87th and fought the fortified enemy positions on the Corps’ northern flank. CCA went on to occupy Ormont. During the day the 4th Infantry Division made slight territorial gains at the eastern bridgehead over the Prüm River. The division’s 12th Infantry Regiment later crossed the bridgehead. The 6th Armored Division’s Combat Command B conquered Matzerath while improving its positions to the south by sending out strong reconnaissance patrols. Combat engineers completed a Bailey Bridge in Lunebach. On the southern flank of the Corps, in Waxweiler, the 6th Cavalry Group (Mechanized) finished crossing a recently completed bridge over the river. The 6th Reconnaissance Squadron conquered Lascheid while the 28th Squadron occupied Lambertsberg and Hargarten. The attack against Plütscheid was unsuccessful, though. The XII Corps continued to advance to the north between the Prüm and Nims Rivers. The 80th Infantry Division’s 317th Infantry Regiment occupied Oberweiler and Schleid while its sister 318th Infantry Regiment commanded by Col James S. Luckett advanced southward to the 76th Infantry Division’s zone. In the sector between the Nims and Kill Rivers, the 4th Armored Division’s Combat Command B received direct aerial and artillery support and conquered Sefferweich and Malbergweich. The 5th Infantry Division held positions along the western bank of the Kyll River. The 76th Infantry Division mopped up the area southwards towards Trier. The division’s 417th Infantry Regiment occupied Mohn and Newel, and advanced to the Kill River near Kordel. Its sister 304th Infantry Regiment took Olk and the 385th Infantry Regiment crossed through the village. The 304th then continued southward."
