These initial delays went far to wreck the whole scheme, because of the food problem. Each of the columns had to bring its own provisions with it, and, when stopped on the road, consumed stores that had been intended to serve it during the siege. The distance from Vejer to Tarifa is only thirty miles, and from Los Barrios to Tarifa even less: but the columns, which had been ordered to march on December 8th, did not reach their destination till December 20th, and the communications behind them were cut already, not by the enemy but by the vile weather, which had turned every mountain stream into a torrent, and every low-lying bottom into a marsh. The column with the siege artillery arrived two days later: it had got safely through the defile of Torre Peña: the sappers had repaired the road by the water, and had built a masked battery for four 12-pounders and two howitzers, whose fire kept off from the dangerous point several Spanish and English gunboats which came up to dispute the passage. The column from the pass of Ojen had been somewhat delayed in its march by a sally of Ballasteros, who came out from the Gibraltar lines on the 17th-18th and fell upon its rear with 2,000 men. He drove in the last battalion, but when Barrois turned back and attacked him with a whole brigade, the Spaniard gave way and retreated in haste to San Roque. Nevertheless, by issuing from his refuge and appearing in the open, he had cut the communications between the army destined for the siege and the troops at Malaga. At the same time that Ballasteros made this diversion, Skerrett, with his whole brigade and a few of Copons’s Spaniards, had issued from Tarifa to demonstrate against the head of the approaching French column, and advanced some distance on the road to Fascinas, where his handful of hussars bickered with the leading cavalry in the enemy’s front. Seeing infantry behind, he took his main body no farther forward than the convent of Nuestra Señora de la Luz, three miles from the fortress. On the 19th the French showed 4,000 men on the surrounding hills, and on the 20th advanced in force in two columns, and pushed the English and Spanish pickets into Tarifa, after a long skirmish in which the British had 31, the Spaniards about 40 casualties, while the French, according to Leval’s report, lost only 1 officer and 3 men killed and 27 wounded. By four in the afternoon the place was invested--the French pickets reaching from sea to sea, and their main body being encamped behind the hills which command the northern side of Tarifa. They could not place themselves near the water, owing to the fire of two British frigates and a swarm of gunboats, which lay in-shore, and shelled their flanks all day, though without great effect.
