With a team of five archaeologists, Oppenheim planned a digging campaign that began on 5 August 1911. Substantial amounts of equipment were imported from Germany, including a small steam train. The costs totaled around 750,000 Mark and were covered by von Oppenheim's father's banking fortune. On arrival, the archaeologists discovered that since 1899 locals had uncovered some of the findings and heavily damaged them – in part out of superstition, in part to gain valuable building material. Oppenheim had recruited five hundred locals from Tell Halaf to help towards the excavation.
