When were the first troops sent to Afghanistan?

As a subject matter expert on military history, I can provide a detailed account of the timeline of the initial deployment of troops to Afghanistan following the tragic events of September 11, 2001. The situation in Afghanistan was a critical juncture in the global fight against terrorism, and the international response was swift and decisive. English Response: On October 7, 2001, the United States, alongside the United Kingdom, initiated military operations in Afghanistan. This marked the beginning of the U.S.-led coalition's efforts to dismantle the Taliban regime, which had provided safe haven to al Qaeda leader Osama bin Laden, the primary suspect behind the 9/11 attacks on the World Trade Center and the Pentagon. The initial strategy involved a combination of airstrikes and special operations forces on the ground to support the Northern Alliance, an Afghan opposition group. The airstrikes were aimed at weakening the Taliban's military capabilities and targeting al Qaeda training camps. These operations were crucial in disrupting the command and control of the Taliban and al Qaeda, and they paved the way for the ground offensive that followed. By November 13, 2001, the sustained air assaults had significantly degraded the Taliban's fighting strength, leading to their abandonment of the capital city, Kabul. This was a significant milestone in the conflict, symbolizing the collapse of the Taliban regime's control over the country. At this point, the number of U.S. troops involved in the offensive was reported to be around 1,300. The deployment of troops was not limited to airstrikes and special operations. As the campaign progressed, conventional forces were also sent to Afghanistan to secure areas liberated from Taliban control, to support the establishment of a new Afghan government, and to conduct counterterrorism operations against remnants of al Qaeda and the Taliban. The war in Afghanistan was a complex and protracted conflict that evolved over the years. It involved not only military operations but also nation-building efforts, including the training of Afghan security forces, the development of governance structures, and humanitarian assistance to the Afghan people. Throughout the conflict, the international community faced numerous challenges, including the resilience of the Taliban insurgency, the difficult terrain and weather conditions, and the complex ethnic and tribal dynamics within Afghanistan. Despite these challenges, the coalition forces made significant efforts to stabilize the country and to support the Afghan government in its fight against terrorism. Dec 1, 2009, is a date that marks a significant shift in the strategy of the U.S. and its allies in Afghanistan. It was around this time that President Barack Obama announced a surge in U.S. troop levels in Afghanistan, aiming to bolster the efforts against the resurgent Taliban and to accelerate the training of Afghan security forces. The war in Afghanistan was a significant chapter in the history of international counterterrorism efforts. It involved a large-scale commitment of military, financial, and diplomatic resources from the international community. The lessons learned from this conflict have had a profound impact on the strategies and tactics used in subsequent counterterrorism operations around the world. **
