An Escalatory Round in Yemen: Mutual Gains and a Battle Heading Toward the Coast and Bab al-Mandab

Yemen’s western and southwestern fronts have witnessed a rapidly escalating military situation since the large-scale Houthi offensive on September 3, which brought Taiz and the western coast back into the spotlight amid intensifying hostilities.

While the escalation began with a Houthi attack targeting government forces’ positions, the battle quickly evolved into counteroffensive operations backed by military reinforcements and airstrikes, alongside military activity in Marib and Al-Jawf. This trajectory raises a key question: Are we witnessing a limited war of attrition, or the beginning of a gradual return to a broader war?

September 3 Attack

The Houthi offensive began at dawn on September 3 across several fronts in Taiz Governorate, including Maqbana, Al-Tuwair, Al-Ahtoub, Al-Kadha, Al-Kuwaicha, Al-Barh, and areas toward Al-Wazi'iyah, using artillery, mortars, missiles, drones, and medium- and light-caliber weapons.

The Houthis managed to seize control of several positions, including Qahban, Jabal Al-Sheikh Saeed, and Jabal Nu'man in the Jabal Habashi area of Taiz, before the clashes spread to wider areas.

According to field reports, the offensive was not merely an attempt to seize forward positions, but rather a move with interconnected objectives, most notably threatening the Taiz–al-Mokha road, severing the Taiz axis from the coastal forces, dispersing the government forces' reserves, and protecting Hudaydah from any counter-move.

This explains the widening scope of the offensive from its very first hours: the Houthis sought to achieve a ground breakthrough that could alter the nature of the front lines, rather than merely securing limited tactical gains. 

However, the swift response by government forces, including redeployment and the arrival of reinforcements from the army, coastal forces, and Aden, prevented the offensive from developing into a decisive breakthrough.

The Taiz–Al-Mokha Battle 

Al-Kadha (Taiz) quickly became the most important focal point of the battle, not only because of the positions it contains, but also because of its location, which links the areas of Jabal Habashi, Maqbana, and Al-Wazi'iyah with roads leading to the coast. Local sources reported that the Houthis managed to reach the Taiz–al-Mokha road and set up checkpoints along parts of it.

The significance of this lies in the fact that control of the road gives the Houthis the ability to exert pressure on the movement of troops and supplies between Taiz and the coast. Al-Barh represents another key junction along this route, given its connection to roads leading to the western coast, Hudaydah, and Hays.

The government forces therefore deployed reinforcements to retake the positions they had lost in Al-Kadha and Maqbana and prevent the Houthis from consolidating their positions along the Taiz–Mokha road. 

This was accompanied by heavy fighting and attempts to advance toward other areas, making control of the high ground and secondary roads a decisive factor in determining the course of the battle.

In other words, the current battle in Taiz is not about isolated villages and positions, but rather about the corridor linking the city to the coast. Whoever succeeds in consolidating their control over it will gain a significant military lever for shaping the battle along the entire western front.

Counterattack

The government forces did not stop at containing the Houthi offensive; they moved instead to a counteroffensive along several axes. Reinforcements from the Giants Brigades and the Nation’s Shield Forces arrived on the western coast and in western Taiz, alongside operations in Hays and areas adjacent to Al-Jarrahi. The government forces announced that they had retaken positions around the Al-Barh junction and advanced westward, while also announcing the capture of Hays and the securing of the district.

In the south, government forces made advances on the Hayfan front in Taiz, taking control of high ground such as Al-Wathrah, Saeed Taha, Dhiban, Al-Khudayrah, and Al-Najdayn. These positions overlook supply and movement routes between southern Taiz and northwestern Lahij.

However, regaining the initiative does not yet mean a definitive change in the map of control. The battle has remained fluid, with the Houthis still holding positions that enable them to put pressure on the roads, while government forces seek to turn the new reinforcements into a continuous ground offensive extending from Hayfan through Maqbana, Al-Kadha, and Al-Barh, all the way to the coast.

This is where the key test lies: Can the government forces move from reacting to events to dictating the tempo of operations? If the reinforcements translate into sustained advances, the nature of this round could change. But if they stop after retaking some positions, the fronts could quickly return to a pattern of attrition.

Government Air Power: The Most Significant Military Shift 

The most notable feature of the current round is the relatively intensive use of government air power. The air force has carried out more than 15 strikes against Houthi positions, gatherings, and vehicles in Taiz and along the western coast, with a focus on supply lines and areas where reinforcements are being assembled.

This represents an important shift in the nature of the operations. The airstrikes are not merely providing support to forces along the front lines; they also give them the ability to strike reinforcements before they reach the battlefield, which could limit the Houthis’ ability to capitalize on their initial gains.

The combination of air power, artillery, and drones also enables government forces to exert broad pressure without having to deploy large ground units along every axis. However, this development has another dimension: the more both sides rely on air power, the greater their ability to keep the conflict open across multiple fronts, potentially prolonging the escalation rather than bringing it to a swift conclusion.

Marib and Al-Jawf: Is the Theater of War Expanding? 

The clashes were not confined to Taiz and the western coast. In parallel, Marib and Al-Jawf witnessed increased use of drones, airstrikes, and artillery against Houthi positions and movements, while airstrikes in Al-Jawf targeted positions, facilities, weapons depots, and fortifications inside Al-Hazm.

However, the available information does not point to a large-scale ground offensive or a fundamental change in the map of control on either of these fronts. At this stage, the apparent objective is to increase pressure on the Houthis, prevent the transfer of reinforcements, and stop them from exploiting the escalation in Taiz to open parallel fronts.

This point is particularly significant because the expansion of military activity into Marib and Al-Jawf means that the escalation is no longer confined to the Taiz–coast battle, but is beginning to take the form of simultaneous pressure along multiple axes. Nevertheless, it is still too early to regard this as the beginning of a full-scale offensive.

The Houthis and Their Attempt to Regain the Initiative 

In contrast to the government forces’ relative air superiority, the Houthis have maintained their reliance on missiles and drones. The clashes have seen the use of drones, including fiber-optic-guided suicide drones. Government forces managed to shoot down two of them, in addition to destroying two explosive-laden boats and downing other drones.

Sources cited by Sheba Intelligence reported possible Houthi preparations to launch ballistic missiles from areas in Hudaydah toward Mokha and Khokha, potentially targeting operational facilities used by the National Resistance and Giants Brigades forces. 

However, the same source stressed that it was not independently possible to verify the missiles’ readiness or the timing of any potential launch.

These developments reveal an apparent Houthi attempt to offset the pressure on the ground and from the air by shifting part of the battle deeper into the rear and threatening the bases and facilities on which government forces along the coast rely. 

If this pattern develops further, the conflict could become less focused on the front lines and more centered on strikes against command, supply, and mobility hubs behind them.

Gains Made by the Government and the Houthis

Despite the continued fighting, the contours of each side’s battlefield gains have begun to emerge. The most significant gain for the legitimate government so far appears to be the recapture by government and joint forces of Hays District and the securing of its rural areas, alongside the recapture of positions at the Al-Barh junction and advances along the western Taiz axes.

Hays is particularly important because it is a geographic hub linking the western coast with the governorates of Taiz, Ibb, and Hudaydah. This makes consolidating control of the area a potential base from which to advance toward wider areas in southern Hudaydah. 

Government forces have already announced the beginning of an advance toward Al-Jarahi in Hudaydah, giving this axis significance that extends beyond simply retaking positions lost during the Houthi offensive.

However, these gains do not mean that the legitimate government has won the battle. The high ground and routes in western Taiz, particularly around Al-Kadha and Maqbana, remain a key obstacle to consolidating the advance and protecting the road linking Taiz and al-Mokha.

Therefore, the real significance of liberating Hays will be determined by the government forces’ ability to link their advances along the coast with developments in western Taiz and turn scattered gains into a continuous operational campaign.

By contrast, the Houthis have not yet achieved a battlefield gain on the scale of sustainably controlling a city or decisively altering the lines of control. However, they have achieved important operational gains. 

They have expanded the scope of the fighting, forced government forces to distribute their reserves across several axes, threatened the Taiz–al-Mokha road, and demonstrated an ability to combine ground attacks with pressure from missiles and drones.

In this way, the Houthi offensive succeeded in shifting the battle from static fronts into a broader and more costly theater for government forces, even though the Houthis failed to retain a large portion of their initial gains.

Military sources also indicate that the group deployed African fighters, including combatants from the Somali militant group al-Shabaab, to the Taiz and western coast fronts, revealing the expanding range of its methods for mobilizing fighters. 

In this way, the Houthi offensive succeeded in shifting the battle from static fronts into a broader and more costly theater for government forces, even though the Houthis failed to retain a large portion of their initial gains.

Here, the Iranian dimension becomes more apparent. Houthi pressure does not rely solely on ground advances, but on integrating ground attacks with missile and drone capabilities, keeping the government’s rear areas and the western coast under threat and increasing the cost of the government forces’ advance.

The battle along the coast takes on additional importance because of its proximity to Bab al-Mandab, which represents a strategic pressure point that Iran can exploit through the Houthis against the United States and regional states, foremost among them Saudi Arabia. 

The more the Houthis maintain their military capabilities near the coast, the greater their ability to threaten maritime navigation and raise the cost of pressure against them. 

Therefore, the battle along the coast is not only about control of territory, but also about who possesses the leverage over one of the region’s most important maritime corridors.

A War of Attrition or a New War? 

The current information does not indicate a return to full-scale war in Yemen, but it clearly goes beyond the pattern of limited clashes that prevailed during periods of calm. 

The Houthi offensive was followed by a government counteroffensive backed by military reinforcements and intensive use of air power, alongside an expansion of pressure into Marib and Al-Jawf and the emergence of threats involving missiles and drones.

This means that the fronts have entered a broader round of escalation, although it has not yet developed into an open war across all lines of contact. The Al-Kadha–Maqbana–Al-Barh axis and the Taiz–al-Mokha road remain the center of gravity in this round.

The Houthis’ control of the high ground overlooking the road and their ability to consolidate positions there would give them greater capacity to exert pressure on lines of movement and supply. For government forces, however, retaking these positions is an essential condition for turning the counteroffensive from a military reaction into an organized advance.

Accordingly, the government’s recapture of a number of positions does not necessarily mean that it has fully regained the initiative. The decisive criteria are its ability to consolidate its gains, secure supply lines, link the various combat axes, and maintain pressure on the Houthis for long enough to bring about a shift in the balance along the front.

The mobilization of multiple formations, including the Giants Brigades and the Nation’s Shield Forces, also demonstrates an ability to reinforce the battlefield. However, this alone is not sufficient to establish the existence of a joint operational command capable of managing a multi-axis offensive.

The Houthis have so far been unable to turn their initial gains into a decisive strategic breakthrough. However, they have succeeded in expanding the area of fighting, forcing government forces to disperse more widely, and opening more than one axis of pressure.

Therefore, the continuation of the fighting over the coming days will be more significant than the results of the initial hours. If the fronts settle into a cycle of advances and withdrawals, the round will remain within the framework of an expanded war of attrition. 

But if either side manages to consolidate its battlefield gains and alter the lines of movement and supply, the round could develop into a new phase in the course of the war.

Accordingly, the current escalation represents a test of the government forces’ ability to translate their mobilization and air superiority into sustainable battlefield gains, against the Houthis’ ability to retake their positions and prevent a shift in the balance along the front.

So far, there are not enough indications of a full-scale war. However, the continuation of military operations and the expansion of their axes make this round more dangerous than previous rounds of escalation, and make the coming days critical in determining whether it ends in mutual attrition or opens a new path toward a broader confrontation.
