Did you know… at the Fortress of Almeida, the French attack plan of 1810 was very similar to the Spanish plan of 1762?

On Napoleon Bonaparte’s birthday, “siege operations began on 15 August, and by the 26th, 11 batteries had already been positioned. Thirteen hours after the bombardment began, a bomb struck the powder magazine, causing the explosion of 4,000 projectiles, 150,000 pounds of gunpowder (approximately 68 tonnes of gunpowder), and almost one million cartridges. With the fortifications destroyed, the population of Almeida surrendered on 28 August 1810. (...)

The attack plan was similar to the Spanish plan of 1762, positioning the army between the River Côa and the town, with the main line of attack directed against the bastions of Santo António and São Pedro and the Breach Ravelin. To this end, the first two parallels were constructed; the third, or Breach Parallel, remained unfinished and is represented by dotted lines on the plan (although the parallels were longer than those of the eighteenth century, allowing more artillery batteries to be positioned).”
