After the fall of the forts at Salamanca, the heavy Artillery employed there continued to be attached to the reserve Artillery under Colonel Dickson, and followed the movements of the army during the campaign. It consisted of three 18-pounder guns on travelling carriages, and five 24-pounder howitzers, to which were attached Captain Glubb’s company of the Royal Artillery, commanded by Captain Power, and a company of Portuguese Artillery, commanded by Major Arriaga, with some additional detachments of the Artillery of both nations. After the battle of Salamanca, the whole eight pieces were brought forward to the neighbourhood of Madrid, preparatory to the attack of Fort la Chine, which was still occupied by the French, but which ultimately surrendered without a contest. On the 1st September, Lord Wellington quitted Madrid, to proceed to Arevalo, where the 1st, 5th, 6th, and 7th Divisions were ordered to assemble preparatory to a movement to the northward; and Colonel Dickson, with his 18-pounders and howitzers, was ordered to accompany this corps. Previous to this movement, measures had been taken to bring forward from Ciudad Rodrigo the following proportion of ammunition, viz.-- 24-pr. round shot 600 18-pr. ” 800 with powder, and all necessary small stores. On the 9th September, this small siege-train arrived at Valladolid, and on the following day continued its march towards Burgos. On the 19th, the Castle of Burgos was invested, the Artillery park being formed near Villa Toro. That Lord Wellington undertook this siege with wholly inadequate means has been well known; but how inadequate these means were will appear from the following statement. First, as regards _personnel_: how many Artillerymen had he to carry on the duties in the batteries against a place which held a commanding situation, and was powerfully armed? He had merely No. of men. Capt. Glubb’s company, under Capt. Power 45 Lieut.-Col. May’s company under Lieut. Elgee 45 Major Arriaga’s company of Portuguese Artillery 57 --- Total 147 --- As mentioned above, he had only eight guns; and the following was the total ammunition of all sorts, including the additional supply from Ciudad Rodrigo. 24-pr. round shot 900 24-pr. common shell 208 24-pr. spherical case 236 18-pr. round shot 1306 18-pr. spherical case 100
