Greek cousins Vs Russian cousins
The execution of the Russian Imperial family prompted a quick response from George to V to rescue his Greek cousins, Prince and Princess Andrew of Greece and their family in 1922.
Since I am studying Greek modern History as a hobby I must point out a few things here. First of all, Alexandra , the Grand Duchesses and the Tsarevitch were held along with the Tsar, while Princess Andrew and her children were safe, it was only Prince Andrew who was facing charges . They were not arested, they were not charged of anything, they were not under house arrest they were not even forbidden to leave the country ,they were not moved, they stayed in their palace in Corfu . So I could say that it was pretty easy for Alice to leave Greece along with her children if she felt she was threatened . I don't see them need any kind of "rescue" not at least in the sense Empress Alexandra and her children needed.
Secondly king George V was able to help Andrew because it was a different situation than that of the Tsar. the Tsar was considered de facto guilty for every act he commited on his whole reign, a potential threat ot the new regime and was relocated so he could not escape . Prince Andrew on the other hand was put under house arrest in Athens ,the country's capital and was facing specific charges. He was charged of high treason on the grounds that when he was a major general of the Greek Army in Asia Minor, he purposely disobeyed his commander in chief and his disodedience contributed in the greek Army's defeat so he was to bet put in trial. Nicholas was said something like " you are responsible for numberless crimes against the soviet people and we are executing you and your family without a trial because we want no one to survive" ,Andrew was said something like " you are charged with high treason and you will face a court".
It is important to know that Andrew was OFFICIALLY charged while Nicholas wasn't, because we can see that in Andrew 's case George V knew that his cousin was facing the highest possible penalty (execution) while he had at least the alibi of uncertainty in Nicholas case. And Andrew wasn't the only one charged with high treason , other six ex - commanders and politicians also faced the same charges in a higly published trial . (in Greece this trial is Known as the Trial of the Six and it is an important historical event) This means that Ceorge V had a lot of time to act until the trial was finished. Moreover, the British diplomacy was able to greatly pressure the greek government to spare Andrew 's life while they didn't have that ability in Nicholas' case. I mean, Greece was crying at the time for foreign financial support , over 1,5 million of refugees had just arrived from Asia they couldn't turn UK against them. Lenin on the other hand didn't need this knd of immediate support from UK.if the Bolsheviks wanted to kill the Imperial Family they could probably get away with it. If Greeks executed P Andrew they couldn't.
In the end it was decided that P ANdrew was to be put to trial alone and the other six together. The other six were all found guilty and were sentenced to death. Prince Andrew was found umanismously innocent due inexperiency in military matters and was banned for life from Greece. He then left he country with his family.
to conclude , George V was able to help his Greek cousins because he could intervene without risking ANYTHING.Unfortunately fo his Russian cousins , he didn't have the same luxury.
