A friend of mine has often related a somewhat humourous story of an Irishman in World War 2 (presumably fighting in the British Army) who captured a bridge using "The Gift of The Gab".
Apparently he walked, possibly unarmed, up to the German checkpoint, proceeded to "inspect" the bridge, then went to the officer in charge and managed to convince him that Germany had ceded that bridge to the allies and that they needed to move back.
On hearing this, the German unit packed their things and withdrew and so the bridge was captured without a shot being fired.
Is there any truth to this story? The friend has quite a bit of military knowledge and I don't really doubt his word, but as I haven't managed to find any references to it online I think there may be a bit of hearsay involved.
