To the best of my knowledge (and my ageing memory) there were no criticisms aired, either politically or in the press, of the guys who fought down south in 1982.
If they had not had inspired leadership on the ground and if they had not been the best in the world at what they had to do (a very dirty war when taking the mountains) the conflict would not have had the result it did. Circumstances often dictate that war is not the clinical affair that those not in the know would advocate. Taking a machine gun post on a mountain, at night and in sh***y weather may well have resulted in all of the ‘defenders’ getting wasted, even those who wanted to surrender (‘cos even bad guys observe the Convention when surrendering). Unlucky.
