While looking into the war history for an uncle that served with the 11 Airborne Division, I came across an original document detailing the operations of the 6th Army in The Battle of Luzon. This came from the 6th ID site. It was written 2 months before the invasion and shows the plan with objectives. Very Impressive ! 6th Infantry Div Plan of Attack | 6th Infantry 6th Infantry Div Plan of Attack | The Sightseeing Sixth Infantry
Steve-I noticed your reference to the 11th AB and wanted to send you a link. It's from our site, tankdestroyer.net, and this is the page for the 637th TD Bn. They were attached, at times, to parts of the 11th during the Luzon campaign. Item #2, Operational Reports, contains their S-3 report and also contains numerous maps. I don't know if this will be of any use to you, but maybe? 637th Tank Destroyer Battalion
Thanks, Steve. This was a most impressive document. I'll have to look at the battle to see how closely it followed the plan. (my guess is not very)
