Campaigns of the Caribbean
Despite word of an imminent invasion coming, Santo Domingo’s military garrisons commander General Alfonso Diaz had let many opportunities to further build up his defenses slip through his fingers. Though Diaz had emplaced shore batteries in & around the city of Santo Domingo & move much of his army into the city the British troops, who were for the most part leading the invasions first wave, & Americans would begin landing east of the capital with relatively few amounts of combat casualties. As British & American units moved inland to establish a secure beachhead, over the next week boats would continue to offload the remaining forces & supplies. By September 1 over 8000 US troops under General Martin & nearly 2500 British troops under General Winston Stephens would be ashore & ready to move on the islands capital city of Santo Domingo.
Though informal allies & supposedly to be conducting this campaign together Martin & Stephens would soon find themselves in disagreement. Stephens would call for a campaign through the island wreaking havoc & forcing General Diaz to come out Santo Domingo & face the allies in open battle where, despite troops numbers being nearly the same, Stephens would be sure that the better equipped & experienced American & British troops could easily win the day. Martin on the other hand called for the immediate move on Santo Domingo & place the city under siege, where there troops combined with the navy offshore he was certain that the city would soon fall, & the allies rear guards could keep the remaining regulars & irregulars remaining in the countryside at bay. As the two generals resolved their attack plans, several miles inland an advanced unit of 400 British soldiers would come under attack on September 2 by 1200 irregulars outside Guerra in the first “major” land engagement of the campaign.
The attack would come at mid morning when the Santo Domingan’s, armed with 2 cannon, would begin firing on the British positions while their troops advanced. Though outnumbered 3-1 the British troops, better trained, equipped, & fighting from a fortified position, would begin to respond with their own 3 cannon firing first standard rounds & then canister shot into the oncoming troops. The untrained & untested irregulars would have no chance & within an hour after sustaining 485 killed, wounded, & captured to Britain’s 97 killed & wounded the Santo Domingan’s would retreat ending the Battle of Guerra. The British victory at Guerra would further cement Stephens opinion that forcing Diaz into an open battle would be the way to go & on September 5 would begin moving his force deeper inland while Martin would move his troops towards Santo Domingo staying close to the coast & under naval protection. Though the two forces had parted ways Stephens agreed that if Diaz hadn’t left the city to attack either force he would circle around & attack Santo Domingo from the west & contribute his troops to the siege.
As Martin would begin slowly moving towards the capital Stephens army would begin cutting a path through the island heading northwest. Aside from small one sided battles against irregulars at Yamasa & Peralvillo though Stephens force would move freely without any significant confrontation as Diaz would continue to keep his army stationed in Santo Domingo to defend the capital. By September 20 Martins force would be nearing the capital & Stephens, whose plan had only succeeded in using up supplies & costing him several hundred casualties, mainly to disease from the harsh climate, would finally & reluctantly turn his army towards Santo Domingo.
Despite Stephens hopes of his troops fighting the first large battle against Diaz on September 23 it would actually be Martin & his Americans who would get that honor when Diaz & 4000 of his 11,000 or so troops would engage Martin just a few miles from Santo Domingo. The Battle of Arismar would begin around 1015 when the two opposing cannon batteries would begin dueling one another & bombarding each others troops. At 1030 the first small arms engagements would occur as each sides units would begin probing each others lines looking for weak spots to push through. However by noon all this probing had done was given each side several casualties & each side would begin to dig in. Though near the coast by 1300 the Americans had yet to receive naval support in dislodging the Spaniards. Unknown to Martin this was due to his armies movement into territory that Spain’s shore batteries covered & the Anglo-American fleet off shore was having a tough time silencing those guns. Despite the allied fleet grossly outnumbering the number of shore batteries it would be most of the day, actions by Royal & US Marines, & cost two ships before enough guns could be silenced that the ships could begin attacking Diaz.
As the Battle of Arismar raged General Stephens would be crossing the Rio Isabella in his movement to encircle Santo Domingo. As his army was still crossing they would be attacked bay 2200 regular & irregular troops & 6 cannon under Colonel Francisco de la Fuentes. The attack would catch the British off guard & Stephens force would suffer several casualties before he would be able to form up his units to defend the still crossing troops. The Battle of Rio Isabella would last only 50 minutes before Stephens, whose force had suffered over 300 total casualties, would be force to withdraw back across the river & retreat. Stephens would retreat several miles before stopping that night & digging in prepared for a secondary attack that he thought would be emanate. However by the next day he would discover that that would not be so as Colonel de la Fuentes had withdrew back into the capital. Though Stephens would not know why, on the 26th he would cautiously begin moving once more to encircle Santo Domingo. It would only be later that Stephens would learn the reason for de la Fuentes’s retreat had occur several miles to the southeast where the Americans had been battling at the Battle of Arismar.
After silencing the shore batteries, the Anglo-American fleet had began bombarding Diaz’s position during the night, causing a significant damage & casualties. Before dawn Martin would order his men forward in a daring night attack on the Spanish lines hoping to catch the Spaniards tired & off guard. The plan worked & before Diaz could effectively move his troops to defend against the oncoming Americans, Martin’s troops were already through Diaz’s front lines & were rapidly advancing on his reserves. By 0730 with much of his force overrun Diaz would retreat back into Santo Domingo defeated. The Battle of Arismar was a decisive victory for the US as they had inflicted 1400 dead & wounded casualties on Diaz & nearly 1600 others were either captured or missing.
With a large portion of his regular troops now destroyed hope for counter attacks to save Santo Domingo from siege looked grim & aside from skirmishes & delaying actions Diaz would never again engage the Americans in open battle. On October 3 the Siege of Santo Domingo would begin as Martin’s & Stephens forces began to dig in around the city. One by one American & British troops & Marines would silence the shore batteries & by the 7th British & US warships would begin bombarding the city. Despite the siege & bombardments Diaz & Santo Domingo would manage to hold out for over three months before on January 9,1808 with his army & Santo Domingo’s populace starving, sick, & dying General Diaz would surrender to Stephens & Martin ending the Siege of Santo Domingo.
