B. Cruisers
1. Puma-Class
Although each of these three small cruisers differed from the others in size and armament, they are best treated as one class. The class ship Puma was laid down at Trieste in 1888 as a half-sister to the contemporary Austrian Tiger, herself based on the British-built Leopard, which in turn was a faster variant of the earlier Mexican Rio Grande. She was identical in every respect to Tiger, and delivered in 1891.
Puma was part of a two-ship order, but the second ship Jaguar was modified to incorporate a more efficient arrangement of her 120mm guns; unlike her half-sister, she had searchlights upon completion and two more 47mm guns. She was laid down in 1889 and delivered in 1892. Due to storm damage suffered during the transit across the Atlantic, she needed repairs after reaching Tampico, and she was not commissioned before 1894.
By that time, the Tampico Naval yard had already laid down an improved and enlarged version of the basic pattern. Ocelot was longer, over 200 tons heavier and carried two more 120mm guns; the torpedo tubes were of larger caliber and relocated to a submerged position. Speed and range were the same; installed hp had been increased by experimentally installing Belleville watertube boilers, which gave a lot of trouble during the first five years. Ocelot was commissioned in 1896.
Together, these three little cruisers formed the scouting squadron of the Mexican battle fleet in the Cuban war 1898. Both at Mayaguana and at Santiago, they engaged Spanish light forces; Puma damaged the Spanish destroyer Osado and torpedoed the unprotected cruiser Reina Mercedes, which was later finished off by a Mexican torpedo boat. Ocelot sank the torpedo gunboat Filipinas and damaged the scout cruiser Murcia. Puma and Ocelot were damaged themselves, but only Puma seriously. After reconstruction, Puma emerged with more powerful 120mm guns, three new 66mm/45 guns and only two 47mm guns; the torpedo caliber was increased to 450mm. The structural damage suffered could however not be fixed satisfactorily, and she was limited to 15 knots afterwards. She was down-rated to a gunboat in 1907.
Jaguar was similarly reconstructed in 1906/7, but landed her 47mm guns altogether in favour of four 66mm/45 pieces. In 1909, she became one of the first Mexican warships to receive a w/t rig.
Ocelot belonged to the Mexican armada during the Venezuelan crisis. Like all Mexican ships, she remained undamaged. She received newer 120mm guns in 1910; secondary armament now consisted of six 66mm/45 Skoda guns. She went to the China station in 1911, where she was scheduled to remain for three years.
Puma paid off in 1912 and was scrapped by 1914. Jaguar, which was still in fine shape, was sold to Colombia in 1914, where she remained in active service till 1932, when she was hulked. The hulk lingered till 1955; her ultimate fate is unknown. Ocelot left Qingdao in August 1914 and made the voyage across the Pacific. She was then part of the Mexican Pacific squadron, whose destruction she missed because of repairs to her engines. She made it to Acapulco after the fall of Tolopobampo, where she was when the Empire fell. Being below 2.000 tons, she was allowed to be retained by the Mexican navy, but during the civil war, she was left to rot and was in an unserviceable state in 1920. Nevertheless, she was refurbished at Veracruz from 1923 to 1925 and remained in service till 1938, when she was replaced by a large Thiarian-built gunboat. Her hulk was scrapped in 1943.

2. Tenochtitlan-Class
Like the preceding class, these three vessels are best treated as the same type despite the last unit’s considerable differences. The first two were Mexico’s first large (by international standards, second class) protected cruisers, based upon the Austrian Kaiser Franz Joseph design and ordered at STT in 1889. Tenochtitlan was laid down in 1890 and delivered in 1893, Acapulco was laid down in 1891 and delivered in 1895. They differed from their Austrian half-sisters by mounting lighter armament; after the sobering experience with the ram cruiser Corona, the Mexicans stipulated only 150mm guns for this class of general-purpose cruisers. On the plus side, they were somewhat faster, capable of over 20 knots.
Both differed only in minor detail; Acapulco had no shields to her 150mm guns and two more 47mm pieces.
Guadalajara, the third unit of the class, was laid down in Tampico in 1892, after modified plans which allowed for less refined construction methods, resulting in considerably larger size; she was seven meters longer, slightly wider and almost 600 tons heavier. She also received Belleville watertube boilers and required less superstructure due to the more spacious hull. Main armament, protection and speed were the same, but the secondary battery was stronger, and four submerged 450mm torpedo tubes were provided. Construction proceeded slowly, and the ship was not delivered before 1897, achieving FOC early in 1898.
All three units took part in every engagement of the Cuban war. Acapulco emerged undamaged and Guadalajara suffered only slight damage, but Tenochtitlan was badly shot up at Santiago and only barely made it home. She needed till late 1900 to return to service. The first two were reconstructed in 1904/05: their main armament was replaced by newer model 150mm guns and moved up to upper deck level for increased seaworthiness, their secondary battery was unified with ten 47mm guns, the torpedo tubes were replaced by larger caliber ones and moved below the waterline, and more extensive bridge facilities with modern fire control gear were installed. Acapulco was present off La Guaira during the second Venezuelan crisis without engaging the enemy. In 1912 and 1913, respectively, they both received w/t gear, among the last Mexican cruisers so refitted.
Tenochtitlan was refitted at Tampico, and Acapulco, which also received a large spotting top, at Veracruz; the shape of the w/t antenna differed considerably, which was a trademark of the Veracruz naval yard.
Guadalajara went to refit in 1907 at Tampico; being of more advanced design than her half-sisters to begin with, she was modified less extensively. Her main armament was exchanged with newer model 150mm pieces, and all guns were redistributed and shielded. W/t gear was added in 1914.
In 1916, the first two units were in reserve. Acapulco was never re-activated, but Tenochtitlan was manned by reservists and sent to Chetumal, where she was duly destroyed by US battleships shortly before the eponymous battle. Acapulco was scuttled at Veracruz when the Empire collapsed; she was salvaged in 1925 and scrapped. Guadalajara was in active service, participated in the siege of Tampico and provided effective fire support for the defenders. She was sunk by gunfire from USS Maine and Ohio during the preparatory bombardment before the final assault.

3. Monterey
This attempt at a large second class protected cruiser was a rather qualified success. For the first time, the design was drawn up all new by the Mexican Navy, rather than copying an extant British or Austrian type, and the lack of design experience told. Although the required twelve 150mm guns were provided, only half of them were available on each broadside; the ship was no better protected than the smaller Tenochtitlan-class, and two knots slower. She was a bad roller and an indifferent sea boat, and handling was poor.
As Tampico was fully occupied at that time and Veracruz not yet able to build ships of that size, the cruiser was ordered at the CNT yard in Austria. She was built quickly and delivered in half the time Tampico needed for Guadalajara, and in the Cuban war, Monterey was fully worked up and flew the flag of Rear Admiral Villaraca. In the battle of Mayaguana, she came under whithering fire from the Spanish armored cruisers Princesa de Asturias and Vizcaya and was reduced to a wreck; when she capsized and blew up, most of her crew including the Admiral were killed.

4. Infanta Isabel-Class
Among other things, the 1892 fleet expansion program called for two first class cruisers; the only extant Austrian armored cruiser, the Maria Theresia, was useless as a template on account of her small size and poor seakeeping. The Mexicans turned to Armstrong for a suitable design, and within weeks, the British yard produced an upscaled version of a cruiser offered to Chile (which would become the O’Higgins). Admiral Beltran liked the ship and immediately placed an order for two hulls, under the condition that the first one was laid down immediately, before the Chilean ship. As the Mexicans paid better, Armstrong complied. The Mexican armored cruiser had the same length as the Chilean ship, but was beamier and 400 tons heavier; protection and speed were the same, but main armament was strengthened by substituting two 152mm guns with 203mm pieces. The first ship, Infanta Isabel, named for the heir to Mexico’s throne, was laid down in 1895 and delivered late in 1897; the second hull was started in 1897 and delivered late in 1899.
A brand new Infanta Isabel stood in the Mexican battle line at Mayaguana and Santiago; during the latter engagement, she was responsible for sinking the Spanish cruiser Cristobal Colon, despite the inexperience of her green crew. By all accounts, she was the best ship in the Mexican fleet at that time. Her sister reached Mexico shortly before the turn of the century; Duque de Tampico – named for Admiral Tegetthoff’s official title – differed in secondary armament distribution and some smaller details, like ventilators and the lack of flag facilities.
Both cruisers formed the vanguard of the Imperial battle fleet for ten years and repeatedly faced off US naval forces during various interventions in smaller Central American nations. Duque de Tampico sank the Portuguese cruiser Dom Carlos during the Venezuelan crisis. In 1910 and 1912, respectively, both had their secondary armament reduced and redistributed to increase seakeeping; fire control was revamped and w/t equipment was added.
Both now resembled each other more than before the refit; Infanta Isabel could be told apart by the empty casemate amidships, whereas the central casemates were removed on Duque de Tampico. The latter also landed the aft pair of torpedo tubes.
Both went to Tolopobampo late in 1914 to bolster the Mexican Pacific fleet; they were the first Mexican warships to pass the Panama channel. They were both present at the battle of Banderas, where Infanta Isabel was blown up from safe distance by USS Enterprise. Duque de Tampico managed to escape the massacre, dealing heavy damage to the armored cruiser USS St.Louis in the process; by the time she reached Tolopobampo, US ground forces were already descending upon the base, and she had to turn around. When coal had run out, she dropped anchor in the Bahia Concepcion, awaiting supplies which never came. After the fall of the Empire, the cruiser surrendered to the Americans and was scrapped in San Francisco in 1921.

5. Veracruz-Class
Monterey’s shortcomings – particularly her low speed – were apparent before she was complete, and the Imperial design bureau prepared an improved version for the remaining two large cruisers of the 1892 program. They were laid down in 1896 and 1897 at Tampico and Veracruz, respectively. Ironically, the Tampico-built ship was named Veracruz, and the other one Zaragoza. With the experience gained from building previous cruisers, the Mexican naval yards delivered much improved quality, in less time and at lower cost per ton. Both ships differed visibly from each other: Veracruz was somewhat shorter, and her sixteen Thornycroft-boilers discharged through two funnels.
Zaragoza had eighteen Belleville-boilers and three funnels. Due to her slightly lower designed hp, Zaragoza had the same speed as her sister; both outpaced Monterey by nearly five knots. Armour protection and coal capacity also were increased, although installation of four of the guns in upper deck casemates impaired seaworthiness.
Both ships were rated as fast and economic steamers, and their habitability made them very popular with their crews. They were very active during the 1900s all around the Caribbean. During the Venezuelan crisis, both belonged to the Mexican armada. Zaragoza sank a Portuguese destroyer and made port at La Guaira to show support to the Venezuelan cause. Veracruz was comprehensively modernized in 1912/13. Her main guns were replaced with more modern pieces and moved to upper deck level, the secondary battery was strengthened, w/t gear and modern fire control equipment was installed.
Zaragoza’s modernization 1914/15 was even more thorough; her casemates were removed entirely, and she received a primitive kind of director fire control.
Both cruisers were based at Chetumal in 1916 and went raiding as soon as the war was declared, in an attempt to disperse US naval forces. Unfortunately, Veracruz was torpedoed and sunk by USS C4 in the Caribbean without having captured a single enemy ship. Zaragoza, operating north of the Spanish Main, was more successful and captured seven US merchants; no less than five US cruisers were dispatched to hunt her down. On August 7th, 1916, she was sighted and engaged by USS Minneapolis, a dedicated commerce raider herself, and got the better of her in a four-hour engagement. But just when Minneapolis was ripe for the kill, USS Brooklyn caught up and opened fire. Critically short of coal, Zaragoza managed to escape the US armoured cruiser, but needed to seek shelter in British waters in the Bahamas. She was interned there for the remainder of the war and surrendered to the USA after the Empire fell. She was broken up in the US in 1924.

6. Cuitlahuac-Class
The 1903 program – the first acquisition of warships after a five-year hiatus – most prominently included the big battleship Victoria, but also two scout cruisers to augment the ageing Puma-type ships, which could no longer keep up with the fleet. They were designed by the Imperial design bureau, based on the Austrian Zenta-class, but a lot bigger, faster and more seaworthy. Cuitlahuac was built at Tampico and completed first in September 1906. Cuauhtemoc was simultaneously laid down at Veracruz, but took a year longer to complete. She differed from Cuitlahuac in lacking the latter’s four 47mm guns, her torpedo tubes were submerged, and she differed in sundry hull and rigging details not readily apparent from a distance. Most importantly, she had four-shaft Parsons turbines instead of VTE machinery; she was marginally faster than her sister, broke down a lot more often and had less range, but was invaluable to the Imperial Navy’s engineering department in gaining experience with the new type of machinery.
The class ship was one of the first Mexican cruisers to receive w/t late in 1909.
When the new 100mm/55 Skoda QF gun became available, which had twice the ROF of the 120/45, longer range and better accuracy, it was decided to rearm these cruisers with the new guns in 1914. Cuitlahuac swapped them one for one, and also received a 66/50 AA gun in lieu of two of her 47mm guns.
Her sister was more comprehensively rebuilt; she landed her entire 66mm secondary battery save a single HA gun and mounted ten of the new 100mm pieces. She also received a tripod mast and a primitive fire control director.
Both vessels went to the Pacific fleet late in 1915, the last Mexican warships to cross the Panama Channel. Cuitlahuac shared the fate of most of the squadron, torpedoed by a US destroyer in the initial phase of the battle of Banderas; Cuauhtemoc managed to escape the carnage together with the armored cruiser Duque de Tampico. She was surrendered to the USA when the Empire collapsed and sunk as a bombing target in 1923.
