Heinrich Schliemann, Troy
In 1872, a monumental excavation force was put together by Heinrich Schliemann to excavated Troy. Using 150 workmen (on average), Schliemann (with his rail engineer on the rock) was able to displace great quantities of debris (over 250,000 cubic meters in three years). An army of 6 horse carts, 10 handcarts mounted upon a rail line and 88 wheelbarrows was assembled by his railroad engineer to achieve this feat.
