The battle took into effect as the result of the Battle of Hamdh. A force of three to four thousand Ikhwan, bedouin fighters led by Faisal Al-Dawish, attacked the Red Fort at Al-Jahra, defended by fifteen hundred men. The fort was besieged and the Kuwaiti position precarious; had the fort fallen, Kuwait would likely have been incorporated into Ibn Saud's empire. In the event, reinforcements from Kuwait City arrived by sea, and help was provided also by Shammar tribesmen who arrived over land.
The Ikhwan attack repulsed for the while, negotiations began between Salim and Al-Dawish; the latter threatened another attack if the Kuwaiti forces did not surrender. The local merchant class convinced Salim to call in help from British troops, who showed up with airplanes and three warships, ending the attacks.

"Fighting between Kuwait's forces and Wahhabi supporters of Ibn Sa'ud broke out in May 1920, and the former were soundly defeated. Within a few weeks, the citizens of Kuwait constructed a new wall to protect Kuwait City."
