That wave arrived at the port around 6 a.m. and started bombing the US ships. Americans were caught completely unprepared and disorganized. Japanese planes succeeded to destroy most of the US ships, but not the main targets though. This mission's primary objectives were to destroy fuel tanks, US carriers and destroyer ships. Most of the destroyer ships were sunk but some of fuel tanks and most of carriers were not reachable for the Japanese due to their inability to find them (they were hidden in barracks and inside the harbor). In addition to this, the main three carriers (Lexington, Enterprise and Saratoga) were not in the port when the attack took place. They were out in the sea and the Japanese did not know it. Due to not achieving to complete primary tasks and returning, makes this attack overall a failure.
