While we were in Malaya in the mid/late 60's, one of our NS Lieutenants (Lt 'flip' McEwan as I recall.....) would take us interested blokes out for a week or so to follow the retreat of the Brits and Aussies et al South down the Malay peninsula. One of his little gems was the jungle clad wreckage of Marmon Herrington gun tractors etc etc, down a ravine where they were destroyed. I believe that they were fairly well South but the only bridge, at the Muar river crossing at Parit Sulong had been taken so no MT could move south any more.
'Flip' was interesting because he was a History Grad who could speak a bit of Malay and speak to the villagers. Bearing in mind that it was only 25 or so tears afterwards. They knew where all the 'stuff' was to be found.
