I am a man of many colors

In this way, with ten warriors, I built a series of three steps from the ground to the shoulders of the topmost man.  Then starting from a short distance behind them I ran swiftly up from one tier to the next, and with a final bound from the broad shoulders of the highest I clutched the top of the great wall and quietly drew myself to its broad expanse.  

After me I dragged six lengths of leather from an equal number of my warriors.  These lengths we had previously fastened together, and passing one end to the topmost warrior I lowered the other end cautiously over the opposite side of the wall toward the avenue below.  No one was in sight, so, lowering myself to the end of my leather strap, I dropped the remaining thirty feet to the pavement below.
