Kesselring was defiant until his death 15 years after the war. Good for him. He exhibited no remorse for being a good soldier.
The Wikipedia entry on Kesselring is very interesting.
The death verdict against Kesselring unleashed a storm of protest in the United Kingdom. Former British Prime Minister Winston Churchill immediately branded it as too harsh and intervened in favour of Kesselring. Field Marshal Alexander, now Governor General of Canada, sent a telegram to Prime Minister Clement Attlee in which he expressed his hope that Kesselring’s sentence would be commuted. “As his old opponent on the battlefield”, he stated, “I have no complaints against him. Kesselring and his soldiers fought against us hard but clean.” Alexander had expressed his admiration for Kesselring as a military commander as early as 1943. In his 1961 memoirs Alexander paid tribute to Kesselring as a commander who “showed great skill in extricating himself from the desperate situations into which his faulty intelligence had led him”.
