Following America's return to Nicaragua in 1926, the United States Marines took command of the Nicaraguan National Guard to fight Sandino's rebels and an occupation began which lasted for several years. In early September, First Lieutenant Chesty Puller discovered a trail which seemed to be the route used by the rebels in their southward thrusts. Chesty Puller returned to Jinotega and with Gunnery Sergeant William "Ironman" Lee organized a strong force of forty guards for a raid like patrol against the rebels. Because both Puller and Lee were technically part of the National Guard, Puller assumed the rank of captain and Lee a first lieutenant. The Nicaraguan national guard force under the command of Puller and Lee left on September 20. After traveling a distance, the patrol moved northwest from the bank of the Auyabal river. On September 26, 1932, the patrol was ambushed by a volley of rifle fire. Ambushes at river crossings were very common during the occupation so Captain Puller and his guards had no trouble in fending off the attack. A quick charge sent the attackers scurrying, for this was merely an attempt to harass the patrol. Lieutenant William A. Lee using a Lewis machine gun kept the enemy pinned down while the Nicaraguan guard worked their way up the slope opposite the rebel ambush party. When they gained the crest, they were able to fire directly into the rebel emplacements. pg. 33.
