"1872 yılında, Mary Celeste adında bir gemi Atlas Okyanusu´nun kuzeyinde, rüzgar ve akıntının etkisiyle sürüklenirken bulundu. Üstelik bordada hiç kimse yoktu. 

Mary Celeste´nin mürettebatı yok olmuştu! Bazı insanlar geminin dev bir ahtapot tarafından saldırıya uğradığını düşünüyordu."

I tried the translation, the general meaning is this:

" In the year 1872, a ship called Mary Celeste has been found on the north of the Atlantic ocean after being carried away by wind and current/flow. In addition there was nobody on board.

The ship´s crew of the Mary Celeste has disappeared! Some people have been thinking that the ship has been attacked by a giant octopus."

I had explained it before. It is the same grammar rule, so look at this link and read my explanations. If you still have questions, I´d answer.

thank you from me too - but can you just explain geminin please?

 "geminin uğradığı" is a compound noun.(http://www.turkishclass.com/turkish_lesson_35   It is formed with the same rule/logic as we form the sentence for example "Adam´ın evi" (Adam´s house)

Adam´ın evi

Geminin uğradığı

If he doesn´t see the relation between nin in geminin and ı in uğradığı, the word geminin alone probably will sound absurd to a learner.

The second ı in uğradığını shows that the word is the direct object of the sentence and answers the question "what did they think?"

Bazı insanlar (geminin dev bir ahtapot tarafından saldırıya uğradığı)+nı düşünüyordu.

Some people thought that the ship was attacked by a giant octopus.

thanks scalpel**.  maybe I´m being very thick but that lesson is pretty complicated!  I understand the basic rules behind compound nouns but all that was really doing my head in!  So what exactly is the translation for ´geminin uğradı´ as a compound noun?  Is it ´the ship´s defeat´?  I saw ´saldırıya uğramak to be attacked, come under attack´ in the site dictionary and so didn´t associate ´uğradını´ with ´geminin´ for that reason.
