"They had seen much of the world get conquered by the British Empire and they knew that whenever they could help anyone that had been oppressed by the British Empire, they should."

I'm not familiar with anything that would support this assertion. The British, in the interest of preserving both the continental and imperial balance of power, was actually committed to preserving Ottoman territorial integrity throughout the 19th century. This was perhaps most powerfully demonstrated in the British intervention in the two Egyptian-Ottoman wars. To call the Ottomans "allies" of the British might be a bit strong, but an Ottoman empire that could hold off the Russians and preserve the capitulations made to international trade was a major British interest.

Some small exceptions were made for popular causes like the independence of Greece, but particularly after the Edict of Gulhane and the start of the Tanzimat reforms in 1839 British and Ottoman interests were pretty well aligned.
