On the 22nd June, 1772, a Royal Warrant was issued, deciding that Captain-Lieutenants in the Artillery and Engineers should rank as Captains in the Army. Those who were then serving, were to have their commissions as Captain, dated 26th May, 1772; and those who might be subsequently commissioned, from the date of their appointment. The title of Captain-Lieutenant was abolished, and that of Second Captain substituted, in 1804. In 1772 and 1775, the regiment was reviewed by the King—on both occasions at Blackheath. The inspections were very satisfactory; in 1772, "The corps went through their different evolutions with great exactness, though greatly incommoded by the weather, and obstructed by the prodigious concourse of people, which was greater than ever was known on any like occasion." In addition to these reviews, the King visited Woolwich in state in 1773, for the purpose of inspecting the new foundry and boring-room. In the latter, he saw a 42-pounder bored with a new and wonderful horizontal boring-machine. He saw many curious inventions; among others, a light field-piece, invented by Colonel Pattison, "which, on emergencies, might be carried on men's shoulders," and which was tried, "to the great amazement of His Majesty." He also went to the Academy, where he breakfasted; and then inspected the companies which happened to be in Woolwich, with whose manœuvres he expressed the utmost satisfaction. The review was marred by an accident which occurred. "Colonel Broome, in parading in front of the Regiment, before His Majesty, on a very beautiful and well-broke horse, but very tender-mouthed, checked him, which made the horse rise upon his hind- legs, and fall backwards upon his rider, who is so greatly bruised, that his life is despaired of."[26] In 1772, the officers, whose extra pay on promotion had been taken to make up the half-pay of Captain-Lieutenant Rogers, complained of the injustice, and their remonstrances were attended to. A warrant was issued on the 4th August, 1772, directing a vacancy of one Second Lieutenant to be kept open in one of the invalid companies, the pay to be employed towards Captain Rogers's half-pay.
