Battle of Lipantitlan

This November 4, 1835 battle was the bloodiest yet in the so called Texas War of Independence. Supposedly after the Battle of Goliad, only two so called Mexican forts remained in what is now Texas. One was Fort Lipantitlan which was located near San Patricio, Texas. The other, of course, was the Alamo. On November 3, 1835, a man living in San Patricio who sided with whites, persuaded the few men still stationed at Fort Lipantitlan, to surrender to the rebel white Texans, which they did do. After the fort was handed over to the rebel white Texans, they destroyed it. However (this is the suspicious part about this battle), a force of Anishinabe Soldiers had left Fort Lipantitlan earlier to supposedly support the Anishinabe Soldiers at Goliad. It does not add up. Why would the soldiers in Fort Lipantitlan just hand over their fort to the rebel white Texans, when they knew many of their forts soldiers were out supposedly fighting the whites at Goliad and were expected to return to Fort Lipantitlan soon? After the 90 Anishinabe Soldiers reached the vicinity of San Patricio where Fort Lipantitlan was located, they discovered 60 to 70 white Soldiers crossing Nueces River, to return to Goliad (it does not add because it reeks of confusion) then attacked them. The rebel white Texans defeated the larger force of Anishinabe Soldiers in the battle that followed. Anishinabe casualties were 3 to 5 killed and 14 to 17 wounded. White casualties were only 1 wounded. We know something is wrong because of the white casualties. What that means is the whites had new superior weapons. The revolver!
