Army of Portugal, Salamanca 28 April 1812.

His Excellency the Marshal Duke of Ragusa has ordered an officer of his army to accompany as far as Bayonne the English Major, Colquhoun Grant, of the 11th Regiment of Infantry, taken prisoner by the French Army in Portugal. This outstanding officer was found alone with one servant on the flank of our columns: found on him were papers and notes which indicate clearly the role of a man of importance to the English army, having the most accurate and the most detailed ideas of the marches, the composition, the strength and the movement of the French army. Nevertheless, as he was captured in the uniform and badges of an English officer, the Marshal has treated him with great regard and willingly received his parole of honour. Find enclosed a copy of the undertaking he has given. But His Excellency thinks that he should be watched and brought to the notice of the Police.

Your humble and obedient servant, General, Chief of Staff, de la Martinère
