Trehouard was a brave Breton, who had performed a splendid feat during an action at Obligado in La Plata, where he commanded the French portion of an Anglo-French flotilla, sent to force its way up the river, which was blocked by a boom and defended by a number of forts. The little fleet met with an energetic and obstinate resistance.

At San Pedro the steamer emerges from the Parana de las Palmas and enters the main channel of the river. A notable locality a few leagues above San Pedro is the Obligado, where the Parana becomes so narrow that the channel lies within pistol-shot of the right bank.

The payment for the score naturally falls to the lot of the listener or victim, and hence has arisen a saying among Frenchmen in La Plata: "Distrust the gentleman who was at the combat of the Obligado."

One of the English vessels, under a withering fire, cut a chain that barred the channel.

Though thus defeated, Rosas still held out on the banks of the Parana, and had strongly fortified a place called Obligado, rather more than a hundred miles from its mouth, having erected batteries of great strength, and thrown a barrier consisting of a number of empty vessels secured together by iron cables across the whole width of the stream, guarded by an armed schooner and some gunboats.
