Allied buildup in Normandy continues
Monday, June 12, 1944 www.onwar.com
On the Western Front... A third wave of Allied forces has landed. There are now 326,000 troops, 104,000 tons of supplies and 54,000 vehicles deployed in Normandy, France. Elements of US 7th Corps advance across the Cotentin Peninsula and southwest. Also, the 4th Division is engaged at Montebourg, Crisbecq and near Azeville to the northward drive on Cherbourg. The 5th Corps assists 7th Corps and advances toward St Lo. Caumont is captured and Foret de Cerisy and the Bayeux road are reached.
In Italy... The British 8th Army reaches Popoli along the Adriatic coast.
In the Mariana Islands... US naval forces continue attacks on Japanese positions in the island group. They concentrate on Tinian, Saipan and Guam. The Japanese fleets located at Tawitawi and Batjan set sail to counterattack. Admiral Kurita commands a vanguard force while Admiral Ozawa leads the main force. The main force from Tawitawi is sighted and reported by an American submarine. The Japanese have 5 fleet carriers, 2 light carriers, 2 seaplane carriers, 5 battleships as well as several cruisers and destroyers in support. The commander of the Combined Fleet, Admiral Toyoda, realizes that the American forces are numerically superior but he also expects support from the land-based aircraft on the islands. These air assets, however, are being depleted by American attacks.
