Pai Bridge

The bridge over the River Pai is often cited as the most conspicuous evidence of the presence of the Imperial Japanese Army
in Thailand during WWII. Unfortunately the statement is in error, as is much other information about that period . . . .

Text Notes

This page discusses World War II aerial photos taken by the Royal Air Force (RAF) and a US Army Air Force (USAAF) Photographic Reconnaissance Squadron (PR or PRS), and provided on-line by the Geo-spatial Digital Archive Project (GDAP) in its Williams-Hunt Aerial Photograph Digital Collection.[2a]


The Williams-Hunt collection has aerial photo coverage on two different dates for Lampang:[3]

Mosaic locations for Lampang

 

Photomosaic No. 1

A mosaic, outlined in red on the site map above, was assembled by Allied intelligence and published on 15 November 1943:[4]

The following GDAP images were used in the above photomosaic:[5]

and assembled approximatey like this, using Microsoft ICE:[6]

Photomosaic No. 2

The area around Lampang outlined above in blue was recorded on three USAAF aerial photos taken late in 1945:[7]

macrophotomosaic

Lampang is located in the upper right quadrant of the mosaic. The airfield with crosswinds runway looks like a small dagger pointed downward. A higher resolution image is available for download here.

While undated the photos have recently been determined to have been taken late in 1945 (see discussion in footnote 6a below).

The following GDAP images were used in the above photomosaic:[8]

02556.jpg
02557.jpg
02558.jpg

and assembled approximately like this, using ICE:[9]

Note that almost all photos in the Williams-Hunt Collection were taken by the RAF. These three however are among a very few in the collection which were taken by the USAAF, specifically the 40th Photographic Reconnaissance Squadron; hence, the "40PR". Annotations on the negatives read:[10]

annotation for photo 02556

annotation for photo 02557

   annotation for photo 02558


GDAP, the source of these photos, has asked that the following information be included regarding the aerial imagery shown above:

  • Williams-Hunt Aerial Photos Collection
  • Original from the School of Oriental and African Studies (SOAS), University of London
  • Digital Data from Center for Southeast Asia Studies (CSEAS), Kyoto University
  • Digital Archive from Chulachomklao Royal Military Academy (CRMA), Thailand

The 40th PRS is noted only briefly in Wikipedia's
8th Reconnaissance Group.

The characters, 5M135, in the annotations are assumed to indicate that the photos were taken in late 1945. The 5 is the year, 1945; the M seems to be a standard designator in aerial photo work; the 135 is the sequence of the order in the 1945 series, which, with that large number, is assumed to be very late in that year.
