In Kearny's report to the Army Adjutant General in Washington, he reduced the significance of the battle tremendously. He does however recognize the Californios as, "...well mounted and among the best horsemen in the world..." He failed to mention how the cold and wet weather had such an adverse effect on the dragoons performance, as well as the confused situation with Johnstons misunderstanding of "Trot", rather than "Charge". He down-played the role the Navy played in rescuing the dragoons, but rather emphasized that it took two messages to get Stockton to come with reinforcements. Kearny also claimed that the enemy had twice as many soldiers as he did, knowing that the number of soldiers that participated in the battle were about even on both sides because not all of the Americans ended up fighting at the battle.
The Battle of San Pasqual marked America's last defeat or obsticle, before aquiring all of California. On February 2, 1848 the Californios and Americans signed the treaty of Guadalupe Hidalgo, giving all of California to the United States, as well as New Mexico. San Diego became the first county in California, as well as the occupational center for all of California. The first lighthouse was built in San Diego to guide the ships, at night into the new San Diego Harbor. With the land grants that the American government was distributing, the population of California, especially San Diego, began to grow tremendously.
