The Battle of Quebracho (from Punta Quebracho or Narrowness Quebracho) against the Anglo-French invasion fleet, occurred on June 4, 1846, about eight months after the battle of Vuelta de Obligado. The place is about a league north of San Lorenzo, today near the town of Puerto General San Martín, 35 km. upstream of Rosario, province of Santa Fe Anglo-French ships returned to the Rio de la Plata after having been its campaign a total economic and military failure, eight months after had forced the passage northward into the Vuelta de Obligado.

On June 2, 1846the authorities in Goya, Corrientes Province, which confronted with the Argentine Confederation led by Brigadier General Juan Manuel de Rosas, offered a farewell reception and dance in honor of the Anglo-French fleet . The latter departed with 95 ships escorted by 16 British and French warships including the steamship HMS Gorgon totaling 37 guns.

On June 4, the forefront of the fleet of 12 ships and 95 merchant ships full of goods, tried to force their way through the Pass of Narrowness of Quebracho.

The first warships appeared at 10.30 am: HMS Firebrand, HMS Gorgon and HMS Alecto followed by San Martin, HMS Fanny and Procida, in the rear and the Corvette Coquette and the Steamers Lizard and Harpy

Confederate forces of the General Lucio Norberto Mansilla, had three batteries with 17 guns led by Colonel Manuel Virtoin the center was Navy Lt. Col. Juan Bautista Thorne with two batteries and two companies of infantry and, on the other hand, Santa Fe Corps, commanded by Lt. Col. Martin Isidoro Santa Coloma and Lezica.

Approximately 300 meters from the canal were crouching, 750 men of the Argentine Confederation.

At 1045 hours Navy Lt. Col. Alvaro Alzogaray opened fire on HMS Gorgon with Congreve rockets. After 2 hours of fighting the Anglo-French fleet had to retreat to cover the remaining merchant. The HMS Harpy was severely damaged, were also sunk two merchant ships and 4 others were burned to not be captured by Confederate forces. The Anglo-French fleet suffered 60 casualties and Confederate forces had one man dead and four injured including Juan Bautista Thorne who suffered a shrapnel wound in his back.

Six months earlier, against the same invaders, General Mansilla had received a gunshot that practically left him for dead (bout of Vuelta de Obligado), however, within a few hours rose from his tent and kept fighting. Now in Quebracho, returned to the attack shouting "Long live the Argentina sovereign independence."

the combat of the of Quebracho besides its enormous military and political importance, was the final seal of the economic and commercial disaster of an unjust and arrogant company, held by those who, secure in their enormous material superiority with no all human considerations and trampling on the legal  rights of the Argentine Confederation, proposed a substantial dividend.
