Kampfgruppe Lueder, including five Tigers, was one of three battle groups in Operation Eilbote. On 20 January 1943 it crossed Oued Maarouf to reach a mountain pass leading to Sibha (As-Subayhah). The book 'Tigers in Combat 1' states that they returned 'later' for an attack towards Qusseltia on the 21st. The veteran Uffz. Klempcke remembers night fighting around Sibha, implying that their return through this pass was on the 21st.
