In the spring of 1708 the regiment again took the field, and was encamped at Fuente de Sapatores, between Elvas and Campo Mayor. The British division was soon afterwards increased to six regiments, by the arrival of the Thirteenth foot, and a newly raised regiment (Paston’s) from England. The little army in the Alemtejo was commanded by the Marquis de Fronteira, but the characteristic inactivity of the Portuguese occasioned the services of the THIRTY-NINTH to be limited to defensive operations. The regiment was encamped in the autumn at Campo Mayor, and afterwards went into cantonments. [Sidenote: 1709.] The regiment moved from its quarters in the spring of 1709, and became engaged in active operations. It was first encamped near Estremos, and proceeded from thence to Elvas on the 23rd of April 1709; the regiment was subsequently encamped with the army on the banks of the _Caya_, where the Earl of Galway, who had been removed from the army in Catalonia, appeared at the head of the British division. On the 7th of May, the French and Spaniards, commanded by the Marquis de Bay, marched in the direction of Campo Mayor; when the Portuguese generals, contrary to the Earl of Galway’s advice, resolved to pass the _Caya_, and attack the enemy. The Portuguese cavalry and artillery took the lead, and having passed the river and gained the opposite heights, opened a sharp cannonade; but upon the advance of their adversaries to charge, the squadrons faced about and galloped from the field, leaving their cannon behind. The British division, arriving at the moment, repulsed the enemy; the leading brigade, consisting of the Thirteenth, Stanwix’s and Galway’s regiments, commanded by Brigadier-General Thomas Pearce, charging furiously, recaptured the Portuguese guns; but the three regiments, pressing forward too far, were surrounded and made prisoners, and with them Major-General Sankey, the Colonel of the THIRTY-NINTH; and the Earl of Barrymore, together with Brigadier-General Thomas Pearce, fell into the hands of the enemy.
