Canonicus-class monitor

<h2 id="design-and-development">Design and development</h2>
In March 1862, <a href="/facts/United_States_Secretary_of_the_Navy/g5vUGAYA">United States Secretary of the Navy</a> <a href="/facts/Gideon_Welles/5LKW4lju">Gideon Welles</a> wrote a letter advising that the <a href="/facts/United_States_Navy/xYK0fUou">United States Navy</a> would be looking for "harbor and river <a href="/facts/Monitor_(warship)/6RBBEzY5">monitors</a>" to serve in the <a href="/facts/Gulf_of_Mexico/bGE5s57G">Gulf of Mexico</a> and the coast of the <a href="/facts/Atlantic_Ocean/EI4uChIb">Atlantic Ocean</a>. A team, led by <a href="/facts/Alban_C._Stimers/RcVLUKHG">Alban C. Stimers</a>, worked on a design based on a general plan developed by <a href="/facts/John_Ericsson/HAkAYjTH">John Ericsson</a> and in consultation with <a href="/facts/Gustavus_Fox/agV1UbnP">Gustavus Fox</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1">1</a> An initial specification was issued to shipyards on 14 August 1862, that was very similar to the preceding <a href="/facts/Passaic-class_monitor/Ngs0UmmI">Passaic-class</a> monitor, to which 15 firms submitted bids.<a class="footnote-ref" id="fnref:2" href="#fn:2">2</a> Six companies were successful in their bids, consisting of three existing firms, Charles Secor & Co, Harrison Loring and Miles Greenwood, and three new firms created specifically for the task, Alexander Swift & Company, Perine, Secor & Co. and Snowden & Mason.<a class="footnote-ref" id="fnref:3" href="#fn:3">3</a> Nine ships were contracted for, which would be known as the Canonicus or Tippecanoe class.<a class="footnote-ref" id="fnref:4" href="#fn:4">4</a>
The Canonicus class was an enlarged and improved version of the preceding Passaic-class monitors. Their hull lines were improved and designed for a higher speed of up to 13 <a href="/facts/Knot_(unit)/Sho0TF2y">knots</a> (24 km/h), although this was not achieved by the vessels themselves. The class consisted of nine vessels. They had a tonnage of 1,034 <a href="/facts/Builder%27s_Old_Measurement/QxeoNSTq">tons burthen</a> and <a href="/facts/Displacement_(ship)/19jbfNuM">displaced</a> 2,100 <a href="/facts/Long_ton/5ajqnrGq">long tons</a> (2,100 <a href="/facts/Tonne/gMymLmWv">t</a>). The individual vessels varied in their dimensions. <a href="/facts/USS_Canonicus_(1863)/33vtrPf0">Canonicus</a> and <a href="/facts/USS_Ajax_(1864)/Lk9IHR1Y">Ajax</a> were largest, measuring 235 ft (72 m) <a href="/facts/Length_overall/YMeByubQ">long overall</a>, with a <a href="/facts/Beam_(nautical)/kG7egDLm">beam</a> of 43 ft 8 in (13.31 m) and a maximum <a href="/facts/Draft_(hull)/MHGIRjC0">draft</a> of 13 ft 6 in (4.11 m). <a href="/facts/USS_Catawba_(1864)/smQ6eEXG">Catawba</a> and <a href="/facts/USS_Oneota_(1864)/HUFR7zcq">Oneota</a> were 225 ft (69 m) long overall, had a beam of 43 ft 3 in (13.18 m) and had a maximum draft of 13 ft 6 in (4.11 m). <a href="/facts/USS_Wyandotte_(1864)/EUEl4176">Wyandotte</a> was 224 feet 6 inches (68.4 m) long overall, had a beam of 43 feet 5 inches (13.2 m) and had a maximum draft of 13 feet 3 inches (4.0 m). The shortest of vessels of the class, <a href="/facts/USS_Mahopac_(1864)/Ikf7tWqS">Mahopac</a>, <a href="/facts/USS_Manhattan_(1863)/sHqHj4MX">Manhattan</a>, <a href="/facts/USS_Saugus_(1863)/oFRMH2ea">Saugus</a> and <a href="/facts/USS_Tecumseh_(1863)/aIQRbF17">Tecumseh</a>, were 223 feet (68 m) long overall, had a beam of 43 feet 4 inches (13.2 m) and had a maximum draft of 13 feet 6 inches (4.1 m).<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a> Each ship had <a href="/facts/Ship%27s_complement/0WkqapPV">crew</a> consisting of 100 officers and enlisted men.<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a>
The ships were powered by a two-cylinder horizontal <a href="/facts/Marine_steam_engine/222EjKnT">vibrating-lever steam engine</a> developed by Ericsson <a class="footnote-ref" id="fnref:7" href="#fn:7">7</a> that drove one <a href="/facts/Propeller/0IN0JKXC">propeller</a> using steam generated by four horizontal <a href="/facts/Fire-tube_boiler/zppRlEls">fire-tube boilers</a> designed by Stimers.<a class="footnote-ref" id="fnref:8" href="#fn:8">8</a> The engine was rated at 320 <a href="/facts/Horsepower/jRMwmIxA">ihp</a> (240 kW) and propelled the ships at a top speed of 8 knots (15 km/h; 9.2 mph). They carried 140–150 long tons (140–150 t) of coal.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a> Each vessel had main armament that consisted of two <a href="/facts/Smoothbore/T6z0unC3">smoothbore</a>, <a href="/facts/Muzzle-loading/RpJPVv78">muzzle-loading</a>, <a href="/facts/Dahlgren_gun/NSzXEMAg">15-inch (381 mm) Dahlgren guns</a> mounted in a single <a href="/facts/Gun_turret/Rn5mhFdW">gun turret</a>.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a> Each gun weighed approximately 43,000 pounds (20,000 kg). They could fire a 350-pound (158.8 kg) shell up to a range of 2,100 yards (1,900 m) at an elevation of +7°.<a class="footnote-ref" id="fnref:11" href="#fn:11">11</a>
The exposed sides of the hull were protected by five layers of 1-inch (25 mm) wrought iron plates, backed by wood and two iron stringers 6+1⁄2 in (165 mm) deep and 6 in (152 mm) thick for 70 ft (21 m) from the bows, but 4 in (102 mm) elsewhere. The armor of the gun turret, of 21 ft (6 m) internal diameter, and the <a href="/facts/Pilot_house/976E5bHV">pilot house</a> consisted of ten layers of one-inch plates. The ship's <a href="/facts/Deck_(ship)/mpNxwSAl">deck</a> was protected by armor 1.5 inches (38 mm) thick. A 5-by-15-inch (130 by 380 mm) soft iron band was fitted around the base of the turret to prevent shells and fragments from jamming the turret as had happened during the <a href="/facts/First_Battle_of_Charleston_Harbor/Hdo8sYJu">First Battle of Charleston Harbor</a> in April 1863.<a class="footnote-ref" id="fnref:12" href="#fn:12">12</a> The base of the <a href="/facts/Funnel_(ship)/qFM2PKIz">funnel</a> was protected to a height of 6 feet (1.8 m) by 8 inches (200 mm) of armor. A "rifle screen" of 1⁄2-inch (13 mm) armor 3 feet (0.9 m) high was installed on the top of the turret to protected the crew against <a href="/facts/Confederate_States_of_America/jMSDM4q3">Confederate</a> <a href="/facts/Sniper/jCTJcvwx">snipers</a> based on a suggestion by <a href="/facts/Commander_(United_States)/gYDtAxXc">Commander</a> <a href="/facts/Tunis_A._M._Craven/AtJyPsg4">Tunis A.

<h2 id="construction">Construction</h2>
The contract for the <a href="/facts/Lead_ship/s2NkkAdD">lead ship</a>, Canonicus, the first Navy ship to be named for the <a href="/facts/Canonicus/mHB3jVbx">chief</a> of the <a href="/facts/Narragansett_(tribe)/53twgs0X">Narragansett</a>, was awarded to Harrison Loring of <a href="/facts/Boston,_Massachusetts/exjfn6xf">Boston, Massachusetts</a>.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a> Meanwhile Tecumseh, Manhattan and Mahopac had been ordered from Charles Secor & Co of New York City, and the majority of the work subcontracted to Joseph Colwell of Jersey City, New Jersey.<a class="footnote-ref" id="fnref:15" href="#fn:15">15</a> Saugus was built by <a href="/facts/Harlan_%26_Hollingsworth/VEht98ee">Harlan & Hollingsworth</a> at their <a href="/facts/Wilmington,_Delaware/EQuEyMQw">Wilmington, Delaware</a>, shipyard.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a> The contract for Catawba and Oneota were awarded to Alexander Swift & Company and built at their <a href="/facts/Cincinnati/PcyTWhS4">Cincinnati</a>, Ohio, shipyard.<a class="footnote-ref" id="fnref:17" href="#fn:17">17</a> The work was shared with the Niles Works.<a class="footnote-ref" id="fnref:18" href="#fn:18">18</a> Manayunk was ordered from Snowden & Mason and built at their new shipyard at <a href="/facts/Pittsburgh/42yPHyS0">Pittsburgh</a>, Pennsylvania.<a class="footnote-ref" id="fnref:19" href="#fn:19">19</a>
The contracts were issued in September 1862, and the yards incentivised to complete quickly by being given a $500 bonus for each day completed ahead of schedule and a similar penalty for each day late.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a> Despite told to not start without receiving final plans, the contractors were therefore keen to start building.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a> Consequently, when the specifications were issued on 9 October, which differed from the expectations of the yards, there was concern that the boats would work as expected and work was halted. The first set of alterations were not agreed until 22 December, with more changes based on the experience of the First Battle of Charleston Harbor following on 18 June the following year. By this time, the opportunity to receive the bonus had disappeared.<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a>
The changes included rebuilding the turrets and pilot houses to increase their armor thickness from 8 inches (203 mm) to 10 inches and to replace the bolts that secured their armor plates together with rivets to prevent them from being knocked loose by the shock of impact from shells striking the turret. Other changes included deepening their hull by 18 inches (457 mm) to increase the ships' buoyancy, moving the position of the turret to balance the ships' trim and replacing all of the ships' deck armor.<a class="footnote-ref" id="fnref:23" href="#fn:23">23</a>
Completion of Catawba and Oneota was further delayed by the low depth of the <a href="/facts/Ohio_River/wSAPrwfS">Ohio River</a>, which prevented their movement to <a href="/facts/Mound_City,_Illinois/p3RvQNDX">Mound City</a>, Illinois, to complete <a href="/facts/Fitting_out/vlYXgkPC">fitting out</a>. Similar problems were experienced with the Ohio river After her launch was delayed by the very low level of the Ohio River, while fitting out, Manayunk was ripped loose from her moorings and had to be towed back to her berth.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a>

On 22 May 1864, Canonicus, Saugus and Tecumseh protected the transports of <a href="/facts/Major_General/4v4nzpy7">Major General</a> <a href="/facts/Benjamin_Butler_(politician)/qx3XGeQn">Benjamin Butler</a>'s <a href="/facts/Army_of_the_James/YzoFbV9K">Army of the James</a>, supplying the army as it operated on the south bank of the James River during the <a href="/facts/Bermuda_Hundred_Campaign/GHybRtd1">Bermuda Hundred Campaign</a>.<a class="footnote-ref" id="fnref:34" href="#fn:34">34</a> As part of this deployment, Tecumseh sank four <a href="/facts/Hulk_(ship)/dvhg3gW6">hulks</a> and a <a href="/facts/Schooner/MESqdu0m">schooner</a> in an attempt to block the channel. On 21 June, Commander Craven, of Tecumseh, spotted a line of <a href="/facts/Breastwork_(fortification)/ALckbfFp">breastworks</a> that the Confederates were building at Howlett's Battery, and his ship opened fire at the workers. The Confederates replied with a battery of four guns near the breastworks and Saugus and Canonicus joined in the bombardment. A half-hour later, Confederate ships near <a href="/facts/Dutch_Gap/hNHkBeh3">Dutch Gap</a> ineffectively joined in.<a class="footnote-ref" id="fnref:35" href="#fn:35">35</a> Saugus fired thirty-six 15-inch shells, Canonicus fired forty and Tecumseh fired forty-six. Saugus received one hit from a Confederate shell and Canonicus two, but no one was wounded or killed during the engagement.<a class="footnote-ref" id="fnref:36" href="#fn:36">36</a>
After commissioning, Manhattan steamed for the Gulf of Mexico and arrived at the <a href="/facts/Pensacola_Navy_Yard/mBAHnJpH">Pensacola Navy Yard</a> on 7 July, towed by the side-wheel gunboat <a href="/facts/USS_Bienville/xVmSyMKw">Bienville</a>.<a class="footnote-ref" id="fnref:37" href="#fn:37">37</a> The 2,000 mi (3,200 km) voyage was the longest undertaken by an ironclad.<a class="footnote-ref" id="fnref:38" href="#fn:38">38</a> She required nearly two weeks to resupply and to repair damage from two small fires that started after her arrival.<a class="footnote-ref" id="fnref:39" href="#fn:39">39</a> The vessel sailed on and arrived outside <a href="/facts/Mobile_Bay/5N6rP11g">Mobile Bay</a> on 20 July, being joined by Tecumseh on 4 August.<a class="footnote-ref" id="fnref:40" href="#fn:40">40</a> On the following morning, they led the Union fleet attack in what would be termed the <a href="/facts/Battle_of_Mobile_Bay/T7n6Asl0">Battle of Mobile Bay</a>.<a class="footnote-ref" id="fnref:41" href="#fn:41">41</a> The monitors were to concentrate on the Confederate <a href="/facts/Ironclad_ram/woAQJfj3">ironclad ram</a> <a href="/facts/CSS_Tennessee_(1863)/XhyqHpda">Tennessee</a>.<a class="footnote-ref" id="fnref:42" href="#fn:42">42</a> During the battle, Tecumseh struck a "torpedo", as <a href="/facts/Naval_mine/jo9uVY9U">mines</a> were called at the time and sank in 25 seconds.<a class="footnote-ref" id="fnref:43" href="#fn:43">43</a><a class="footnote-ref" id="fnref:44" href="#fn:44">44</a> A boat sent by the gunboat <a href="/facts/USS_Metacomet_(1863)/n3rLw3xy">Metacomet</a> rescued ten men and delivered them to the <a href="/facts/River_monitor/VbSLy3TY">river monitor</a> <a href="/facts/USS_Winnebago_(1863)/FWoEu8Ev">Winnebago</a>.<a class="footnote-ref" id="fnref:45" href="#fn:45">45</a> Seven other survivors reached one of the stricken vessel's boats and four were captured when they swam ashore. 94 died.<a class="footnote-ref" id="fnref:46" href="#fn:46">46</a> The wreck remains under 15 ft (4.6 m) of water.<a class="footnote-ref" id="fnref:47" href="#fn:47">47</a> Manhattan fired a total of eleven shots, six at Tennessee and five at <a href="/facts/Fort_Morgan_(Alabama)/NdIzYkVb">Fort Morgan</a>.

Canonicus, Mahopac and Saugus returned to Howlett's Battery on 5 and 6 December. Mahopac was hit five times and lightly damaged; she fired 41 shells in return, of which six had any effect on the Confederate forces. Saugus fired 14 shells and received only two hits. One of the shots, from a 8-inch (200 mm) <a href="/facts/Brooke_rifle/amHqH635">Brooke rifle</a>, disabled her turret temporarily when it cracked an armor plate and broke a number of 2-inch (51 mm) bolts.

After being was transferred to <a href="/facts/Key_West,_Florida/JvtQRdTn">Key West, Florida</a> In 1870, Manhattan was refitted in 1872–1873 in Philadelphia, returning to Key West for fleet maneuvers before serving off the coast of North and South Carolina from 25 April 1876. After spending time in Virginia at <a href="/facts/Norfolk,_Virginia/PPAclcuM">Norfolk</a>, Brandon, <a href="/facts/City_Point,_Virginia/tyRePUQS">City Point</a> and Richmond, Manhattan was transferred to Philadelphia and laid up at <a href="/facts/League_Island/C0HshYvU">League Island</a> in 1888 before being struck from the Navy List on 14 December 1901 and sold on 24 March 1902 for breaking up.<a class="footnote-ref" id="fnref:64" href="#fn:64">64</a>
Manayunk, Oneota and Catawba had been laid up in ordinary opposite <a href="/facts/Cairo,_Illinois/MNR7hofu">Cairo, Illinois</a> during the civil war. Vulnerable to damage from debris flowing down the river, the Navy finally moved them to <a href="/facts/New_Orleans/IgCn61KH">New Orleans</a> in May 1866.<a class="footnote-ref" id="fnref:65" href="#fn:65">65</a> Renamed Ajax on 15 June 1867, Manayunk was commissioned on 1 January 1871, serving intermittently before being placed in ordinary at Richmond, on 30 June 1891. Similarly, Tippecanoe, by now named Wyandotte, was commissioned on 24 January 1876. Briefly recommissioned for local defense duties in response to the <a href="/facts/Spanish%E2%80%93American_War/ScKbBPAv">Spanish–American War</a>, Wyandotte and Ajax were decommissioned in September 1898 and sold on 17 January and 10 October 1899 respectively.<a class="footnote-ref" id="fnref:66" href="#fn:66">66</a><a class="footnote-ref" id="fnref:67" href="#fn:67">67</a>
Decommissioned on 13 June 1865, Saugus was recommissioned on 30 April 1869 amidst reports of mistreatment of American citizens duringt the <a href="/facts/Ten_Years%27_War/VcRvvEJr">Ten Years' War</a> in Cuba and patrolled along the Florida coast until end of 1870. After being towed to <a href="/facts/Philadelphia,_Pennsylvania/2bFFCCTU">Philadelphia, Pennsylvania</a>, for repairs, Saugus was recommissioned there on 9 November 1872 and was based at Key West until transferred to Port Royal, South Carolina, in 1876. Saugus returned to Washington and was decommissioned there on 8 October 1877 and sold on 25 May 1891.<a class="footnote-ref" id="fnref:68" href="#fn:68">68</a>

<h3>Peruvian service</h3>
In August 1867, the Navy sold Catawba and Oneota back to Swift & Co., contingent on a guarantee that they would be returned in good shape if they could not be sold, and the company began refitting them.<a class="footnote-ref" id="fnref:69" href="#fn:69">69</a> In October 1867, an agent for Swift & Co. negotiated a deal with Peru to purchase the ships for a million dollars apiece. The ships were appraised at $375,000 and $380,000 respectively, and sold for that amount, possibly after a corrupt bidding process, on 11 April 1868.<a class="footnote-ref" id="fnref:70" href="#fn:70">70</a> Catawba was renamed Atahualpa, after the <a href="/facts/Emperor/qhML5ftb">Emperor</a> <a href="/facts/Atahualpa/T9gIHMlN">Atahualpa</a>, the last ruler of the <a href="/facts/Inca_Empire/GjNowI6t">Inca Empire</a> and Oneota became Manco Cápac in honor of <a href="/facts/Manco_C%C3%A1pac/HI2s1xTS">Manco Cápac</a>, the legendary first king of the <a href="/facts/Kingdom_of_Cuzco/7mh8nK15">Kingdom of Cuzco</a>.<a class="footnote-ref" id="fnref:71" href="#fn:71">71</a><a class="footnote-ref" id="fnref:72" href="#fn:72">72</a> To prepare the ships for their lengthy voyage to Peru, around <a href="/facts/Cape_Horn/pQweprXb">Cape Horn</a>, Swift & Co. added a <a href="/facts/Glossary_of_nautical_terms_(A-L)/b2XlMKqN">breakwater</a> on the bow, stepped two masts with a <a href="/facts/Fore-and-aft_rig/CI8uA4CC">fore-and-aft rig</a> to supplement the engines, and provided closures to make vents and deck openings water tight.<a class="footnote-ref" id="fnref:73" href="#fn:73">73</a>
While this was going on, the United States was negotiating with Great Britain over the <a href="/facts/Alabama_Claims/FymSANPS">Alabama Claims</a>, compensation for losses inflicted by British ships knowingly sold to the Confederacy during the Civil War. Peru had been involved in an <a href="/facts/Chincha_Islands_War/Dg9YbyQH">undeclared war with Spain</a>, and the US was not willing to prejudice its claims against the United Kingdom by performing a similar action for a belligerent power.<a class="footnote-ref" id="fnref:74" href="#fn:74">74</a> Negotiations over the issue delayed the departure of the two monitors until January 1869, by which time Peru had bought two steamers, Reyes and Marañon to tow the monitors. Machinery breakdowns meant that, on reaching Pensacola, Florida, they were forced to wait 30 days for repairs to be completed. En route from Key West to <a href="/facts/The_Bahamas/x6VKsUhj">the Bahamas</a>, the ships were separated in heavy weather. Reyes collided with the sharp bow of Manco Cápac and sank in 15 minutes. Short on food, water and fuel, the monitor, was able to send a local schooner to <a href="/facts/Nassau,_Bahamas/6sWIpMeX">Nassau</a> to inform the authorities of their plight. Atahualpa reached <a href="/facts/Great_Inagua/w909mGjp">Great Inagua</a>, in the Bahamas, and was able to resupply, although her officers had to pay for themselves. The ships finally reunited at <a href="/facts/Saint_Thomas,_U.S._Virgin_Islands/0FbUujBo">St. Thomas</a> in the <a href="/facts/Virgin_Islands/PUj4JoGn">Virgin Islands</a> and had to wait for the Pachitea to arrive from Peru to tow Manco Cápac. While entering <a href="/facts/Rio_de_Janeiro/AVPTJJ2C">Rio de Janeiro</a> on the night of 15 September, Manco Cápac ran aground. She was refloated the following day, but the damage required three months to repair. The monitors reached the <a href="/facts/Strait_of_Magellan/eYVjuvtF">Strait of Magellan</a> on 29 January 1870 and <a href="/facts/Callao/GjSCYb0k">Callao</a> on 11 May.<a class="footnote-ref" id="fnref:75" href="#fn:75">75</a>
Atahualpa was towed from Callao to <a href="/facts/Iquique/asCJfgEC">Iquique</a>, then part of Peru, from 11–22 May 1877, to defend that port from the rebel ironclad <a href="/facts/Hu%C3%A1scar_(ironclad)/MmsoF5Yv">Huáscar</a> during the <a href="/facts/Nicol%C3%A1s_de_Pi%C3%A9rola/aUtC22X4">Peruvian Civil War</a>. When the <a href="/facts/War_of_the_Pacific/MgdGmxSo">War of the Pacific</a> with Chile began in 1879, Atahualpa was stationed in Callao and Manco Cápacwas sent to defend Arica. During the blockade of Arica, Huáscar, now in the hands of the <a href="/facts/Chilean_Navy/QhdlTdxq">Chilean Navy</a> after the 1879 <a href="/facts/Battle_of_Angamos/S2SAaFFq">Battle of Angamos</a>, attacked Arica on 27 February 1880, fighting an inconclusive duel with Manco Cápac. After striking the schooner <a href="/facts/Spanish_schooner_Virgen_de_Covadonga/qEFbXpdR">Covadonga</a> on blockade duty on 6 June, Manco Cápac was scuttled to prevent her capture when the city fell the following day.<a class="footnote-ref" id="fnref:76" href="#fn:76">76</a> On 11 December 1880, the Chilean fleet started firing at Callao, at ranges of up to 4 miles (6.4 km). Atahualpa, escorted by a tug, sortied to fight a long-range battle with the Chilean fleet, but failed to inflict any damage.<a class="footnote-ref" id="fnref:77" href="#fn:77">77</a> On 16 January 1881, her crew scuttled her to prevent her capture by Chilean forces as they advanced into the city. She was subsequently raised and sold to be broken up.<a class="footnote-ref" id="fnref:78" href="#fn:78">78</a>
