A photo from 1907 shows a British sailor unshackling an enslaved man who had been chained for three years. The photo was taken by Joseph Chidwick, a crew member of the HMS Sphinx.
Upon discovering the Royal Navy's presence nearby, the man in the photos successfully fled from a slave-trading outpost located off the coast of Oman.
In 2007, Samuel, the son of Joseph Chidwick, gifted this image to the Royal Navy Museum along with the following remarks:
"The pictures were taken by my father who was serving aboard HMS Sphinx while on armed patrol off the Zanzibar and Mozambique coast in about 1907.
They caught quite a few slavers and those particular slaves that are in the pictures happened while he was on watch. That night a dhow (sailing vessel) sailed by and the slaves were all chained together.
He raised the alarm and they got them on to the ship and got the chains knocked off them. They then questioned them and sent a party of marines ashore to try to track the slave traders down.
They caught two of them and I believe they were of Arabic origin.
My father thought the slave trade was a despicable thing that was going on, the slaves were treated very badly so when they got the slavers they didn’t give them a very nice time”.
