Analysis of information sources in references of the Wikipedia article "Battle of Tassafaronga" in English language version.
The Japanese were able to inflict heavy damage on the U.S. ships, but were unable to complete their resupply mission, with deleterious effects for their troops on Guadalcanal.
the naval battles around Guadalcanal were bookended with two of the worst defeats in U.S. naval history (Savo Island and Tassafaronga), eclipsed only by Pearl Harbor.
Thus ended one of the most ignominious defeats in U.S. Navy history, although technically Wright and TF-67 succeeded in their mission, since none of the supplies from Tanaka's destroyers made it ashore to starving Japanese troops on Guadalcanal.
