“Buffalo” fighter in early 1942 markings. These small fighters were completely outclassed by the Japanese Zero.

14 June 4, 1942, First Phase

• Japanese carrier aircraft hit Midway – Japanese carriers launch “half strikes” • Midway planes attack Japanese carriers before Japanese planes return to their carriers – US carriers also launch against the Japanese • US carrier torpedo bombers attack Japanese – 38 of 42 torpedo bombers lost • US carrier dive bombers hit three Japanese carriers & put all 3 out of action

15 June 4, 1942: Second Phase

• Japanese carrier Hiryu launches two attacks – Dive bombers at Yorktown; strike her at noon – Torpedo planes hit her at about 1445, stopping her. She lists heavily and is abandoned. • Enterprise and Hornet launch strikes against Hiryu, bombing and crippling her at about 1700, just as Hiryu is about to launch another strike at the US force
