All these officers, whether commanding-in-chief like Aylmer or in subordinate command like Danby, were serving in a position afterwards known as that of "Commodore." This title, derived from the Dutch "Commandeur" (originally the senior officer of a merchant fleet) which had been adopted in the Dutch navy from their merchant service at the end of the sixteenth century, was introduced into the English navy about 1695, no doubt as a consequence of the close connection between the two navies under "Dutch William." It was, however, not yet officially recognised; in their official orders the officers were simply "Captain" or "Captain and Commander in chief." They received a special allowance, usually 10_s._ a day, while so acting. Later on the importance of some of these positions was enhanced by the introduction, in certain cases, of a second captain into the Commodore's ship. This practice, which was in vogue at least as early as 1720, does not seem at first to have entailed any difference in flag or pay, but it made an important difference in prize money, for those Commodores who had Captains under them were treated in this respect as though they were flag officers. In 1731 the Admiralty attempted to establish the rank of Commodore by providing for three posts of this rank in the _Regulations and Instructions for his Majesty's service at sea_, then for the first time gathered together in one book, but the Privy Council struck out all the articles relating to this proposal before recommending the book for the king's approval. The title was, however, formally recognised in 1734 by an Order in Council which, in laying down the relative precedence of Sea and Land Officers, provided "That Commodores with Broad Pendants have the same respects as Brigadiers-General," but the rank remains to this day a "temporary" one, carrying special pay and privileges but giving the captain holding it no authority over captains senior to him on the list. Regulations governing the rank first appeared in the _King's Regulations_ of 1806. The Broad Pendant was to be of the squadronal colour and was to have the further distinction of a white ball if the Commodore had no second captain in his ship. There shall be a temporary rank of Commodore which shall be distinguished by a Broad Pendant, Red, White or Blue.... If the Commodore commands the ship himself the Pendant shall have a large white Ball near the staff and he shall not rank as a Rear Admiral. Prior to 1806, Commodores appear to have kept their pendants flying in all circumstances. The new regulations, however, directed that if the Commodore met a senior captain, that captain was also to hoist a broad pendant, but if there were more than one senior to him then the Commodore was to strike his broad pendant instead.
