Another matter that worried the combatants was money. War was never a cheap enterprise, and the Russian treasury had less than a year to recover from the strain it went through during the wars of the Third and Fourth coalitions. Worse still was the fact St. Petersburg's entry into the Continental System was beginning to show its effects in the form of a drastic fall in exports and a rise in the prices of luxury goods, to the discomfort of the same elite that murdered Alexander's father and predecessor Paul I. The one sector of the economy that grew was manufacturing, thanks to the lack of British industrialized goods in the Russian market, but it wasn't enough to make up for the problems elsewhere (2).
The Ottoman exchequer was also in a tough spot despite British subsidies, and the people in charge responded in the only way they knew, by raising taxes. This measure worsened a fiscal burden which had only grown since the start of the New Order, and, combined with the harsh winter and the devastation brought about by thousands of soldiers left and right, many of whom stole or extorted money and food from peasants and townsfolk whenever they could, prompted people to become bandits or, worse, rebel against Ottoman authority outright. The worst disturbances and riots happened in northern Bulgaria, especially at
Plevne, and in the sanjak of Nis. The latter was an especially worrying development, since, due to the sanjak's Serbian majority, it was feared the discontent there could spread to Belgrade and spur the
knezes into action. Though indispenisble allies in the supression of the Janissaries, many in Constantinople feared they would defect to the Russians if given a chance, due to their mutual Orthodox faith.
That was exactly what Bennigsen and the other Russian commanders hoped would happen, and because of it they made Vidin the target of their next campaign. It wasn't until Russian troops were sighted in the outskirts of the city in question, in April 2 1809, that the Ottoman leadership, which until then believed their enemies would make another attempt to take Silistra and thus concentrated the bulk of their forces there, realized the enormity of their mistake. To make matters worse, many of Vidin's once fearsome fortifications were neglected or even torn down in the years after Osman Pazvantoglu's defeat, out of fear they could be taken over by another rebel. The end result was that, much like what happened at Rusçuk, the Ottoman garrison surrendered in April 10 rather than keep fighting against impossible odds. The path to Serbia was open, and now all Bennigsen and his colleagues had to do was wait for the
knezes' inevitable rebellion. And so they waited.
And waited.
And waited.
They had seriously underestimated just how loyal the Serbs of Belgrade were to Constantinople now, even those like Đorđe Petrović, who fought against its authority once and was exiled before his eventual amnesty by Hadji Mustafa Pasha (3). They had a status no other Christian population under Ottoman rule possessed, and they weren't willing to risk it to help a foreign army which was facing mounting difficulties since last year. The Russian high command was paralyzed by indecision, with Bagration and like-minded officers calling for an invasion of Serbia to "nudge" the
knezes in the right direction while Bennigsen refused, arguing such a move would strain Russian logistics far too much and turn the Serbs against them for good. This stalemate allowed Muhammad Ali to redeploy the bulk of his forces westward, and prepare an attempt to kick the invaders back to the other side of the Danube.
The two armies clashed at Dunavci, just south of Vidin itself, but the battle that ensued was an indecisive slog since the Russians withdrew to Calafat in good order, despite their inferior numbers. Delayed orders and lack of coordination ruined the day once more, and Moore's men barely saw any action because of this, much to their irritation. Muhammad Ali Pasha hadn't yet scored the great victory he needed to secure an appointement to the grand vizierate, and recapturing Vidin wasn't enough. So he greenlit an advance against Calafat, the first step of a campaign to kick the Russians out of western Wallachia, and hopefully all of it by the end of the year. Calafat fell without resistance in May 4, and two days later 70.000 Ottoman and British soldiers finished crossing the Danube.
It was at this moment, right when Muhammad Ali's grand design was about to unfold, that everything ground to a halt thanks to a panicked report from Constantinople: the French, it seemed, had finally made their move. Having had enough of his brother-in-law's pestering, Napoleon finally authorized the transfer of an army corps of roughly 30.000 men to Dalmatia overland (marching through Austrian territory in the process), after which they were put under the command of the local governor, general Auguste de Marmont. He and his army left Spalato right as the Battle of Dunavci was being fought, and reached the strategic city of
Köprühisar in May 2. The swiftness of his opening move and the ease with which he entered Bosnia soon roused suspicions of collaboration by the locals, since Bosnia was a Janissary stronghold and was engulfed by a revolt that was quashed just before hostilities with Russia began (4).
Still, despite all the panic it caused at first, Marmont's campaign was every bit as doomed as Napoleon's attempt to conquer Egypt and Syria a decade before: he had no real objective beyond stirring things up in western Rumelia and pulling back before the Ottomans smashed him. With Köprühisar secured, his next target was Travnik, then the capital of the Bosnia Eyalet, but it proved to be too tough a city to take, even for the mighty Grande Armée. For starters the terrain separating them from their destination was nothing short of atrocious, with many mountains, hills and forests that provided perfect hiding spots for guerrillas, which were already showing how effective they could be in Spain. Second, all three of Bosnia's main ethnoreligious groups - Orthdox Serbs, Catholic Croats and Muslim Bosniaks - were apathetic to the invaders at best, in case of the first group, or hostile, like the latter two, for reasons ranging from anti-clerical policies back home to bad behavior (read: looting) by the soldiers in general.
The result was that, despite not fighting a single pitched battle whatsoever, Marmont didn't reach the outskirts of Travnik until May 18, much later than he'd planned, and by then the city was abandoned, with nothing worth taking in sight. Despondent and receiving ominous reports that the population of Köprühisar was about to revolt against its occupiers, something that would cut his army's supply line, he ordered a retreat back to Spalato. He had lost a third of the men under his command, most from starvation and disease, though their continuous harrassment by guerrilla bands undermined their morale to an extent Marmont would later call Bosnia "My Little Spain" in his memoirs.
As big a failure as it was, Marmont's adventure still hindered the Ottoman war effort by forcing Muhammad Ali to sit still in Calafat for more than two weeks before it became clear he wasn't going anywhere. This, in turn, gave the Russians the chance they needed to concentrate their forces in the Danubian Principalities for a decisive battle. Trapped on the wrong side of the Danube, the Ottoman and British troops had only one way out if they were defeated. The clash that decided the outcome of the Russo-Turkish War of 1808-1809 was fought at Poiana Mare, just east of Calafat, in May 29 1809. The Ottomans were outnumbered on the battlefield for the first time, with 70.000 of their troops against 80.000 Russians. Their greatest disadvantage wasn't raw numbers, but in how many guns they had, an amount a quarter smaller than what their enemies possessed. If they were to win, they needed to put the right troops in the right places.
