The formation of the school at Chatham increased the means for discipline and drill. Other stations, stimulated by the example, paid greater attention to their enforcement. The injurious system of changing officers incessantly was now abolished; and the juniors, among a stated number of the second captains, first lieutenants, and second lieutenants of the royal engineers, were appointed regimental officers of the companies. Sir John Jones has recorded that “the men generally were of superior acquirements and well-disposed,” and the above changes had the best possible effect upon their general behaviour.[[179]] “By linking officers and men together,” he added, “and closely connecting their mutual interests, discipline and pride were given to the soldier,” and character to the corps.[[180]]

More fully to accord with its recognized duties the Master-General on the 4th August, ordered that the royal military artificers should be hereafter styled, Royal Military Artificers or Sappers and Miners.[[181]]

Captain G. Buchanan, the adjutant, resigned the appointment, and Captain Rice Jones, under commission dated 1st February, succeeded to it. During his period of office, Captain Buchanan, besides attending to its many official requirements and details, performed duty on the works like other officers of engineers. By his application and exertions he ruined his health. Captain Rice Jones was relieved from the duties of the district, and the pay of the appointment was increased from 6s. to 10s. a-day.[[182]]

The siege of Cuidad Rodrigo began on the 8th and terminated on the 19th January when the fortress was carried by storm. In this siege eighteen rank and file of the royal military artificers were present, of whom one was killed and ten were wounded. In carrying on their duties they were sometimes annoyed by the presence of light balls thrown by the enemy into the sap. The instant they alighted some bold sappers, heedless of the peril they incurred, rushed to the spot, and in a few seconds extinguished them with sand-bags or smothered them by shovelling earth upon the flames.[[183]] The conduct of the party during the operations was praised by Lord Wellington.[[184]]

To join the siege party, the fifth company second battalion of forty-one men, had been embodied at Alhandra from the different districts of Torres Vedras, and marched for Cuidad Rodrigo on the 2nd January. It had in charge a large assortment of intrenching tools to be used in the works before that fortress. The weather was bitterly cold, a considerable quantity of rain had fallen, and the roads were cut into deep ruts and covered with pools. Frequently the jaded mules dropped from fatigue; and to relieve them, the men were constantly compelled, either to lead them instead of the disaffected muleteers, or take the labour of the animals themselves. After a trying and toilsome journey of seventeen days, the company arrived in front of Cuidad Rodrigo on the night of the 19th January, but took no part in the storming.[[185]]

The above company and detachment were afterwards employed in restoring and improving the defences of the place. Paid by measurement for their labour, they greatly exerted themselves, notwithstanding the bitter weather to which they were exposed. Corporal James Douglas was intrusted with the charge of the restoration.

In the siege of Badajoz from 16th March to 6th April, the military artificers bore an important part. There were present 115 of all ranks, being portions of the fifth and seventh companies, second battalion, from Cuidad Rodrigo; and the sixth of the second battalion from the Almada position. A company from Cadiz comprising men of the sixth and seventh companies, first battalion, did not join till nearly the conclusion of the siege. The company disembarked at Ayamonte and ascended the valley of the Guadiana on the Portugal side, partly by boats and partly by marching. No British soldiers, save this company, had ever been in that part of Portugal.

All the engineers' means for the operation were conveyed from Elvas to Badajoz under charge of the corps, for which purpose 120 pairs of bullocks were pressed into the service. The effectual removal of the stores was accomplished under great difficulties. From the desertion of the drivers, taking with them their oxen, and the weakly condition of others, many of the sappers frequently yoked themselves to the abandoned burdens, and in carrying them through the Guadiana at the fords, were sometimes borne down the stream by the rapidity of the current. Nearly all the stores, however, reached the depôt at the appointed time.

In the distribution of the men, a strong party was nominated for the duty of the park, to repair tools, make scaling-ladders, platforms, &c., and the remainder, told off into seven brigades, performed good services as overseers and leading sappers in the trenches and the batteries. Sub-Lieutenants A. Wallace and R. Gibb who joined in January, volunteered their services as assistants in the trenches, and both discharged their duties “extremely well.” Their conduct was noticed in flattering terms in a letter to General Mann, the inspector-general of fortifications.

Soon after commencing operations, corporal Patrick Rooney signalized himself by laying gun platforms in the day-time under a warm fire from the enemy. No less conspicuous was private William Harry, who opened in daylight under fire of the Picurina, the embrasures of a masked battery. In executing these dangerous services, their firmness and skill had the effect of stimulating the workmen to the prompt performance of similar exploits.
