The way I've always seen Bastongne is more of an example of the tenacity and resilience of US soldiers who held the line.
Yes Bastogne was an example of very fierce resistance, especially when contrasted by rather quick collapse of the US 106th Infantry Division (which suffered ca. 800 killed and wounded and ca. 7000 captured - having two of its regiments - 422nd and 423rd - totally annihilated) in period 16 - 19 December.
And to sugar this serious defeat, Ambrose ("Citizen Soldiers") made up a patriotic story about one heroic platoon of the 106th Division resisting against supposedly entire regiment of German paratroopers on 16 December, suffering only 1 dead and killing at least 300 Germans in the process.
Just imagine this romantic story - one heroic platoon killing piles of elite German paratroopers, while the rest of the US division is surrendering around it.
The fact that one US platoon for some time managed to hamper an advance of a German battalion, indeed took place (which in itself is a great achievement). Ambrose, however, seriously embroidered this story. Originally it was mentioned by John Eisenhower's "Bitter woods" (but he doesn't write about 300 dead Germans - and he writes that this platoon managed to hamper an advance of one German battalion - rather than entire regiment - for some time).
And when it comes to German losses - entire 9th Fallshirmjager-Regiment (not just one of its battalions) lost
68 dead and wounded on that day.
A platoon holding off a battalion for even one hour - is still an achievement in itself. No need to make up additional stories about 300 dead Germans.
======================================
This is a good example how various true wartime events (a US platoon hampering an advance of a German battalion for perhaps around one hour, inflicting a few casualties on those Germans and suffering 1 dead and perhaps a few wounded in the process) turn into legendary stories (an epic tale about one platoon of US super heroes killing hundreds of Germans and injuring thousands, slaughtering a regiment of elite paratroopers, while only 1 of them dies).
A good example on how various accounts of wartime bravery are being blown up to often ridiculous degree.
