As part of the test mobilisation ships of the three fleets assembled at Spithead for a
Fleet Review from 20 to 23 July. Also assembled were five
flights (A through E) of seaplanes from the
Royal Naval Air Service (RNAS), which had only separated from the
Royal Flying Corps on 1 July. The aircraft, around 17 in total, comprised every serviceable seaplane in the RNAS at that time and included at least three
Short Admiralty Type 74s and a
Sopwith Bat Boat. On 18 July a flypast of 20 aeroplanes and seaplanes led by
Charles Rumney Samson was made over the assembling fleet and around the airships. During the review one of the airships took the first ever aerial photograph from directly above a battleship. The other 30 vessels included
torpedo boats,
depot ships,
submarines and
auxiliary vessels.|left George V arrived at Portsmouth on 20 July aboard the royal yacht
HMY Victoria and Albert. The vessel's captain,
John Ernest Harper, served as master of the fleet for the review. The review was also attended by Churchill.
Victoria and Albert left Portsmouth later on 20 July, escorted by the airships
No.3 and
No.4 to anchor off what is now the location of
Nab Tower. The entire fleet then passed in a single line in front of the yacht for review by the king. Overhead the 17 seaplanes and two formations of aeroplanes carried out one of the earliest recorded instances of close
formation flying by British aircraft, for which they had carried out several weeks of practice at
Eastchurch airfield. Following the review, the vessels involved carried out four days of exercises in manoeuvring and battle practice. These were observed by some of the attendees of the
Cowes Regatta, including
Prince Henry of Prussia, brother of the German emperor, who went on to visit George V at Buckingham Palace to seek assurances about peace between the two nations. ==Aftermath ==
