In a caricature published by Walker in 1808, we see Joseph Bonaparte (one of these Imperial ginger-bread monarchs) driven from Madrid by Spanish flies; the satire is entitled _Spanish Flies, or Boney taking an Immoderate Dose_, and has reference to the results of the Battle of Baylen, in Andalusia, one of the _very_ few victories ever obtained by the Spaniards against the French, where a division of 14,000 men surrendered to Castanos. This was on the 20th of July, and nine days afterwards Joseph retreated to Burgos with the crown jewels. The wretched Spaniards, however, were incapable of improving their victory; and General Castanos instead of following up the retreating enemy, went to Seville to fulfil a vow he had made of dedicating his unexpected victory to St. Ferdinand, on whose tomb he deposited the crown of laurel presented to him by his grateful countrymen. Of the Bonaparte caricatures of this year, no less than nineteen are due to the pencil of Thomas Rowlandson, and will be found fully described in Mr. Joseph Grego's exhaustive work[13] upon that artist and his works.

FIGURES FROM GILLRAY'S NAPOLEONIC CARICATURES. _Face p. 20._] The year 1809 witnessed the divorce from Josephine, and the marriage of the emperor to Marie Louise. The purposes for which this matrimonial alliance was effected were made no secret of by the emperor, and were indicated of course in the plainest possible terms by the English contemporary caricaturists, who were certainly not troubled with any unnecessary scruples of prudery or delicacy. One of these satires, published by Tegg, on the 16th of August, 1810, is entitled _Boney and his New Wife, or a Quarrel about Nothing_, and indicates in the plainest possible terms that the purposes for which the divorce had been effected were as distant as ever. The result of this union, however, was the birth of the young king of Rome on the 20th of March, 1810, an event which set the pencils of our pictorial satirists once more in motion, and the young heir and his father were complimented by Rowlandson in a rough caricature, published by Tegg on the 9th of April, 1811, as _Boney the Second, the little Babboon [sic] created to devour French Monkies_.
