********************D Day, June 1/2, 1942*************
On balance a good day. The landings went very well. A couple of platoons on a USN Port Coy. arrived at Pagan before dawn. About half of them sprained their ankles or foolishly ate some bad shellfish but the rest were OK. The main amphibious group arrived late in the day but they disembarked with little difficulty. About 2/3 of the troops are ashore already in good order but the infantry units have about 40% fatigue from the long trip (and playing craps and a Parchisi marathon on board the night before). Hundreds of sorties were flown by TBF's and dive bombers against the troops on Pagan with only moderate success.
Chicken had moved Judys to Iwo Jima and they and some Nells (also from Iwo) attacked the carriers standing off Pagan with a large fighter escort from both Pagan and Iwo. The Judy attack had 55 Zeroes in escort. They were met eventually with met 180+ F6F's and F4F's. It was a "Marianas Turkey Shoot". Not one bomber even made it to the pickett screen. The Nells came in later with about 35 Zeroes and were slaughtered too. Overall, about 88 Jap planes were lost to 2-3 operational losses for the USN. The USN Corsairs with the northern carriers did not particiapte as they were sweeping over Pagan fruitlessly.
In the South, the airfield raids on Guam went well, driving runway damage up to 80% but Chicken had evacuated the field so only two planes were destroyed on the ground. The small surface group sent to Guam suffered two mine hits on DD's (which will survive) and encountered 3 annoying "groups" of patrol boats in singlets and couplets as well as a nest of fleet subs and minisubs. In the event, the CO of the bombardment group for Guam called off the attack or they stopped for cucumber sandwiches or something...even though they had only 160 miles to target at the start of the night.
At Saipan, the ASW groups and surface groups got distracted by Jap subs on the run in so the bombardment groups arrived first and engaged in a BB vs PB duel at 30,000 yds in daylight, again failing to bombard it's target. Still, it might have been worse as the BB (New Mexico I think) was hit by a dud torpedo from an I boat on the way in.
