Limbers and caissons

Horses pull big carts to move heavy guns.

A limber is a small cart with two wheels. It hooks onto the back of a gun. This helps horses pull the big gun.

A caisson is another cart. It carries extra boxes of supplies. These boxes hold things used with the guns.

Sometimes, these carts carry a casket. This happens at special funerals.

Long ago, horses did all this work. Now, big trucks do it instead. It is a big change!

In the past, horses moved heavy guns. They used special carts to help.

A limber is a small cart with two wheels. It has a metal hook called a pintle. To move a gun, the crew hooks the gun to the limber. This lets horses pull the heavy gun easily.

Limbers also carry ammunition. This is the supply used by the gun. A chest on the limber might hold 28 rounds. These chests are very heavy. One chest can weigh 650 pounds! Crews must push or drag them.

A caisson is a second cart. It carries even more supplies. It holds extra ammunition chests and spare wheels.

Sometimes, caissons are used in funerals. They carry a casket for people in the military. This happens during special ceremonies in places like the United States.

Today, we mostly use trucks to move guns. We do not use many horse teams anymore. But these carts were very important for a long time.

In the past, moving heavy artillery required special tools. A limber is a two-wheeled cart used to tow a gun. It supports the trail, which is the back end of the gun carriage.

When the gun is not being moved, the trail rests on the ground. To move it, the crew raises the trail and lowers it onto the limber. A metal hook called a pintle connects the two pieces. This setup allows horses to pull the heavy equipment easily.

Limbers and caissons work together to keep guns ready for use. A caisson is a second two-wheeled cart meant to carry ammunition.

The limber often holds an ammunition chest on top. This chest might hold 28 rounds for a Napoleon 12-pounder gun. To keep the gunpowder safe, the chest cover is made of copper. This prevents sparks from starting a fire.

A caisson carries even more supplies, like extra chests and spare wheels. It also carries a limber pole slung underneath.

History shows how these tools changed over time. The British developed a new carriage system that the French later adopted.

Americans then copied the French design for their own use. During the American Civil War, many armies used very similar equipment.

Field artillery limbers took on a standard look during this era. They featured two wheels, an ammunition chest, and a pintle hook. This design became the model for many years to come.

Moving these items was a very hard job for the crews. A full ammunition chest for a Napoleon gun weighs 650 pounds.

Because they are so heavy, crews must drag or push them. They cannot simply lift them into place. Six horses were usually the best team for a field piece.

Sometimes, a crew might need ten horses to pull a huge siege gun. This extra strength helps move the massive weight across the ground.

Today, we see these tools in different ways. Most armies now use trucks or tractors instead of horses.

However, caissons are still used in special military funerals. In the United States, they carry caskets at Arlington National Cemetery.

This is a way to show great respect for those who served. Even though technology has changed, these traditions remain important.

Limbers and caissons are specialized two-wheeled carts designed to support and move heavy artillery. A limber serves as a towing vehicle for an artillery piece. It supports the trail, which is the rear part of the gun carriage.

When a gun is not being moved, its trail rests on the ground. To transport the weapon, the crew raises the trail and lowers it onto the limber. A metal hook called a pintle connects the two parts. This mechanism allows horses or other draft animals to pull the heavy equipment efficiently.

These vehicles work in a coordinated system to keep artillery operational. While the limber pulls the gun, a caisson acts as a dedicated ammunition wagon.

The limber usually carries an ammunition chest on top. For a Napoleon 12-pounder gun, this chest held 28 rounds of ammunition. To ensure safety, the chest cover was made of sheet copper. This material prevented stray embers from causing a fire. The caisson carries even more supplies, including two extra ammunition chests, a spare wheel, and an extra limber pole slung underneath.

The logistics of moving these items required significant physical effort and animal power. A full ammunition chest for a Napoleon 12-pounder weighed 650 pounds.

Because of this weight, crews had to drag or push the chests rather than lifting them. For field artillery, six horses were the preferred team, though four was the minimum. Horses were harnessed in pairs on either side of the limber pole. Drivers rode on the near horse, which is the horse on the left side. They held reins for both their own horse and the off horse on the right.

Different types of artillery required different equipment configurations. Field artillery limbers were designed for mobility and included ammunition chests. In contrast, siege artillery limbers were used for much heavier guns and did not have ammunition chests.

Moving these massive siege guns or howitzers required much more power, often needing between six and ten horses. The limber system also supported other specialized wagons. A battery wagon carried spare parts and paint. A traveling forge was used by a blacksmith to repair hardware. The ammunition chests on these wagons carried specific tools for carpenters, saddle-makers, or blacksmiths.

The design of these carriages underwent significant historical development. The British originally developed a new system of carriages. The French later adopted this system, and the Americans subsequently copied it from the French.

By the time of the American Civil War, U.S. Army equipment was essentially identical to Confederate equipment. This equipment was also very similar to what other nations were using. During this era, the field artillery limber reached its archetypal form. This included two wheels, an ammunition chest, a pintle hook, and a central pole for the horses.

During active combat, the placement of these vehicles was carefully managed. The limber was typically kept about six yards behind the artillery piece, depending on the terrain. The caisson was positioned even farther to the rear of the firing line. Ideally, the caisson was placed behind natural cover, such as a ridge. This helped protect the extra ammunition from harm. To maintain a constant supply, crews would exchange the limber and caisson once the ammunition in the limber's chest was exhausted. The middle chest from the caisson would then be moved forward to the limber.

As technology progressed, the role of horse-drawn limbers changed. The widespread use of trucks and artillery tractors eventually replaced horses as the primary movers. Most armies moved away from these systems after the Second World War. However, some designs remained relevant for a time. For example, the British 25-pdr was designed to be towed with a trailer. This trailer provided a vital over-run braking system for the gun. The No. 27 trailer also carried 32 rounds of ammunition and included a stores tray and brackets for a traversing platform.

Despite the shift to motorized transport, caissons maintain a significant role in modern traditions. In the United States, caissons are used to carry caskets during state funerals for government dignitaries.

At Arlington National Cemetery, the Caisson Platoon of The Old Guard performs these duties. In British tradition, the use of caissons for funerals follows specific customs. For the funerals of British monarchs, the horses are replaced by a detail from the Royal Navy. In these instances, the coffin is often placed on a platform atop a gun carriage.
