Late in the afternoon came a thrill when the mule-mounted infantry reappeared, heading up-line towards us. They would pass below our ambush, and Zaal and the men were urgent to attack them on the sudden. We were one hundred, they little over two hundred. We had the upper ground, could hope to empty some of their saddles by our first volley, and then would camel-charge upon them. Camels, especially down a gentle slope, would overtake mules in a few strides, and their moving bulk would send spinning the lighter animals and their riders. Zaal gave me his word that no regular cavalry, let alone mere mounted infantry, could cope with tribal camels in a running fight. We should take not only the men, but their precious animals.
