When they reached the river, the soldiers could not find the ford, so Clinch ferried his regular troops across the river in a single canoe. Once they were across and had relaxed, the Seminoles attacked. The troops fixed bayonets and charged them, at the cost of four dead and 59 wounded. The militia provided cover as the army troops then withdrew across the river. In the Battle of Lake Okeechobee, Colonel Zachary Taylor saw the first major action of the campaign. He left Fort Gardiner on the upper Kissimmee River with 1,000 men on December 19 and headed towards Lake Okeechobee. In the first two days, 90 Seminoles surrendered. On the third day, Taylor stopped to build Fort Basinger where he left his sick and enough men to guard the Seminoles who had surrendered. Taylor's column caught up with the main body of the Seminoles on the north shore of Lake Okeechobee on December 25. The Seminoles were led by "Alligator", Sam Jones, and the recently escaped Coacoochee, and they were positioned in a hammock surrounded by sawgrass. The ground was thick mud, and sawgrass easily cuts and burns the skin. Taylor had about 800 men, while the Seminoles numbered fewer than 400. Taylor sent in the Missouri volunteers first, moving his troops squarely into the center of the swamp. His plan was to make a direct attack rather than encircle the Indians. All his men were on foot. As soon as they came within range, the Indians opened with heavy fire. The volunteers broke and their commander Colonel Gentry was fatally wounded, so they retreated back across the swamp. The fighting in the sawgrass was deadliest for five companies of the Sixth Infantry; every officer but one was killed or wounded, along with most of their non-commissioned officers. The soldiers suffered 26 killed and 112 wounded, compared to 11 Seminoles killed and 14 wounded. No Seminoles were captured, although Taylor did capture 100 ponies and 600 head of cattle. By 1842, the war was winding down and most Seminoles had left Florida for Oklahoma. The US Army officially recorded 1,466 deaths in the Second Seminole War, mostly from disease. The number killed in action is less clear. Mahon reports 328 regular army killed in action, while Missall reports that Seminoles killed 269 officers and men. Almost half of those deaths occurred in the Dade Massacre, Battle of Lake Okeechobee, and Harney Massacre.
