Following his dismissal from his post as governor of the Tower of London after making inappropriate comments about Beefeaters, Maj Gen Keith Cima claimed for unfair dismissal.
He believed that he was sacked by the Tower's management company, Historic Royal Palaces (HRP), because he exposed malpractice at the attraction and also because he confronted the bullies who were previously sacked for their treatment of Moira Cameron, the first female Beefeater.
The man accused of bullying, Mark Sanders-Cook, was later given an apology and a settlement, which Gen Cima opposed saying that HRP had "prostituted itself" by giving Mr Sanders-Cook money.
Gen Cima, who wanted to support Ms Cameron, told the Central Employment Tribunal in London that he "felt as though his position was undermined".
The tribunal heard that Gen Cima was alleged to have described Beefeaters as the "lowest of the low" and "thick".
Michael Day, HRP's chief executive, said that Gen Cima "was often prickly, unnecessarily challenging and confrontational".
He said: "Colleagues did not find him easy to work with in a collegiate way and he did not work in the way that HRP worked."
And when Gen Cima was told of the outcome of Mr Sanders-Cook's settlement, Mr Day said that Gen Cima "behaved like a petulant child, did not make eye contact and shrugged his shoulders."
Mr Day said: "I knew he was upset but it was not an appropriate response for a person occupying this level of post."
At the tribunal in London, Judge Harjit Grewal said that Gen Cima had made "inappropriate, offensive and damaging remarks about HRP as an organisation." He also commented that Gen Cima had "failed to accept that he had done anything wrong or that he needed to change".
HRP said: "We are pleased the employment tribunal hearing has concluded that Gen Cima was fairly dismissed and that HRP was justified in taking the action that it did."
