conversation. Sitgreaves reported that the natives brought many different types of fruits and vegetables which suggested that they were interested in developing trade relations. But the friendliness of the Mohave soon wore off when on one October night, the Americans were growing restless after a long visit from the natives at their camp that they asked them to leave. This upset some of the Mohave women who protested and the next morning several arrows were fired into the camp. One wounded the expedition's doctor in the leg but with his medical experience he was capable of preventing serious harm. Sitgreaves decided it was best to break camp and the Mohave let him without further confrontation. On or about October 22, the Americans reached a friendly Mohave village and learned from a Spanish speaking native that Fort Yuma and the mouth of the Gila River, which connects with the Colorado, was only eight days distant. Again the Americans gave the Mohave elders gifts but they remained on alert, fearing an incident similar to the last.

He was killed and the warriors moved forward to attack Sitgreaves' column. When the captain realized he was under attack, skirmishers were deployed and in a short engagement, four Mohaves were killed and some others wounded. The only American casualty was the first soldier who was relieved of his musketoon when the Mohave retreated. From there the expedition continued on for another week or so until reaching the war zone of Fort Yuma on November 30, 1851, after nearly starving to death and after losing most of their equipment. At the fort Sitgreaves discovered that the outpost was badly in need of provisions also and as a result, the party had to cook and eat all of their mules before making it to San Diego. Aftermath Despite a treacherous journey, the mission was technically a success, the Zuni, the Little Colorado and the Big Colorado were mapped and this intelligence provided westward bound settlers with a possible avenue for emigration. The rivers were found to be fully navigable and from then on a growing number of river steamers and schooners began sailing the Colorado. Captain Sitgreaves made a thorough account of the expedition in his 1854 book Report of an
