left　as　a　pivot；　the　cavalry　joined　in　the　movement；　pressing　forward
  on　the　New　Market　and　Central　or　Charles　City　roads。
  We　did　not　go　far　before　we　found　the　enemy's　infantry　posted　across
  these　two　roads　behind　a　strong　line　of　intrenchments　on　the　west
  bank　of　Bailey's　Creek。　　His　videttes　in　front　of　Ruffin's　house　on
  the　New　Market　road　were　soon　driven　in　on　their　main　line；　and　the
  high　ground　before　the　house　was　immediately　occupied　by　Torbert　and
  Gregg；　supported　by　Kautz's　division。　　By　the　time　the　cavalry　line
  was　formed　the　Confederate　General　Kershaw；　with　his　own　division　of
  infantry　and　those　of　Wilcox　and　Heath；　advanced　to　attack　us。
  Directing　the　most　of　his　troops　against　the　cavalry；　which　was　still
  mounted；　Kershaw　drove　it　back　some　distance　over　the　high　ground。
  When　it　reached　the　eastern　face　of　the　ridge；　however；　it　was
  quickly　dismounted；　and　the　men　directed　to　lie　down　in　line　of
  battle　about　fifteen　yards　from　the　crest；　and　here　the　onset　of　the
  enemy　was　awaited。　　When　Kershaw's　men　reached　the　crest　such　a
  severe　fire　was　opened　on　them；　and　at　such　close　quarters；　that　they
  could　not　withstand　it；　and　gave　way　in　disorder。　　They　were　followed
  across　the　plain　by　the　cavalry；　and　lost　about　two　hundred　and　fifty
  prisoners　and　two　battle…flags。　　The　counter　attack　against　the
  infantry　by　Torbert　and　Gregg　re…established　our　line　and　gave　us　the
  victory　of　Darbytown；　but　it　also　demonstrated　the　fact　that　General
  Lee　had　anticipated　the　movement　around　his　left　flank　by
  transferring　to　the　north　side　of　the　James　a　large　portion　of　his
  infantry　and　W。　H。　F。　Lee's　division　of　cavalry。
  This　development　rendered　useless　any　further　effort　on　Hancock's
  part　or　mine　to　carry　out　the　plan　of　the　expedition；　for　General
  Grant　did　not　intend　Hancock　to　assault　the　enemy's　works　unless
  there　should　be　found　in　them　but　a　very　thin　line　of　infantry　which
  could　be　surprised。　　In　such　event；　Hancock　was　to　operate　so　that
  the　cavalry　might　turn　the　Confederates　on　the　Central　or　Charles
  City　road；　but　the　continually　increasing　force　of　the　enemy　showed
  this　to　be　impracticable。　　The　long　front　presented　by　Hancock's
  corps　and　the　cavalry　deceived　General　Lee；　and　he　undoubtedly
  thought　that　nearly　all　of　Grant's　army　had　been　moved　to　the　north
  side　of　the　James　River；　and　to　meet　the　danger　he　transferred　the
  most　of　his　own　strength　to　the　same　side　to　confront　his　adversary；
  thinning　the　lines　around　Petersburg　to　reinforce　those　opposing　us
  on　the　Central　and　New　Market　roads。　　This　was　what　Grant　hoped　Lee
  would　do　in　case　the　operations　of　Hancock　and　myself　became
  impracticable；　for　Grant　had　an　alternative　plan　for　carrying
  Petersburg　by　assault　in　conjunction　with　the　explosion　of　a　mine
  that　had　been　driven　under　the　enemy's　works　from　the　front　of
  Burnside's　corps。
  Now　that　there　was　no　longer　a　chance　for　the　cavalry　to　turn　the
  enemy's　left；　our　attention　was　directed　to　keeping　up　the　deception
  of　Lee；　and　on　the　afternoon　of　the　28th　Hancock's　corps　withdrew　to
  a　line　nearer　the　head　of　the　bridge；　the　cavalry　drawing　back　to　a
  position　on　his　right。　　From　now　on；　all　sorts　of　devices　and
  stratagems　were　practicedanything　that　would　tend　to　make　the
  Confederates　believe　we　were　being　reinforced；　while　Hancock　was
  preparing　for　a　rapid　return　to　Petersburg　at　the　proper　time。　　In
  order　to　delude　the　enemy　still　more　after　night…fall　of　the　28th　I
  sent　one　of　my　divisions　to　the　south　side　of　the　James；　first
  covering　the　bridgeway　with　refuse　hay　to　keep　the　tram　of　the　horses
  from　being　heard。　　After　daylight　the　next　morning；　I　marched　this
  division　back　again　on　foot；　in　full　view　of　the　enemy；　to　create　the
  impression　of　a　continuous　movement　large　bodies　of　infantry　to　the
  north　side；　while　the　same　time　Kautz　was　made　to　skirmish　with　the
  enemy　on　our　extreme　right。　　These　various　artifices　had　the　effect
  intended；　for　by　the　evening　of　the　29th　Lee　had　transferred　all　his
  infantry　to　the　north　bank　of　the　James；　except　three　divisions；　and
  all　his　cavalry　save　one。
  The　morning　of　the　30th　had　been　fixed　upon　to　explode　the　mine　and
  assault　the　enemy's　works；　so　after　dark　on　the　evening　of　the　29th
  Hancock　hastily　but　quietly　withdrew　his　corps　to　the　south　side　to
  take　part　in　the　engagement　which　was　to　succeed　the　explosion；　and　I
  was　directed　to　follow　Hancock。　　This　left　me　on　the　north　side　of
  the　river　confronting　two…thirds　of　Lee's　army　in　a　perilous
  position；　where　I　could　easily　be　driven　into　Curl's　Neck　and　my
  whole　command　annihilated。　　The　situation；　therefore；　was　not　a
  pleasant　one　to　contemplate；　but　it　could　not　be　avoided。　　Luckily
  the　enemy　did　not　see　fit　to　attack；　and　my　anxiety　was　greatly
  relieved　by　getting　the　whole　command　safely　across　the　bridge
  shortly　after　daylight；　having　drawn　in　the　different　brigades
  successively　from　my　right。　　By　10　o'clock　on　the　morning　of　the　3oth
  my　leading　division　was　well　over　toward　the　left　of　our　army　in
  front　of　Petersburg；　marching　with　the　purpose　to　get　around　the
  enemy's　right　flank　during　the　operations　that　were　to　succeed　the
  mine　explosion；　but　when　I　reached　General　Meade's　headquarters　I
  found　that　lamentable　failure　had　attended　the　assault　made　when　the
  enemy's　works　were　blown　up　in　the　morning。　　Blunder　after　blunder
  had　rendered　the　assault　abortive；　and　all　the　opportunities　opened
  by　our　expedition　to　the　north　side　were　irretrievably　lost；　so
  General　Meade　at　once　arrested　the　movement　of　the　cavalry。
  In　the　expedition　to　Deep　Bottom　I　was　under　the　command　of　Major…
  General　Hancock；　who；　by　seniority；　was　to　control　my　corps　as　well
  as　his　own　until　the　way　was　opened　for　me　to　get　out　on　the　Virginia
  Central　railroad。　　If　this　opportunity　was　gained；　I　was　to　cut　loose
  and　damage　Lee's　communications　with　the　Shenandoah　Valley　in　such
  manner　as　best　suited　the　conditions；　but　my　return　was　not　to　be
  jeopardized　nor　long　delayed。　　This　necessitated　that　Hancock's　line
  should　extend　to　Bottom's　bridge　on　the　Chickahominy。　　The　enemy's
  early　discovery　of　the　movement　and　his　concentration　of　troops　on
  the　north　side　prevented　Hancock　from　accomplishing　the　programme
  laid　out　for　him。　　Its　impracticability　was　demonstrated　early　on　the
  27th；　and　Hancock's　soldierly　instincts　told　him　this　the　moment　he
  unexpectedly　discovered　Kershaw　blocking　the　New　Market　and　Charles
  City　roads。　　To　Hancock　the　temptation　to　assault　Kershaw's　position
  was　strong　indeed；　but　if　he　carried　it　there　would　still　remain　the
  dubious　problem　of　holding　the　line　necessary　for　my　safe　return；　so
  with　rare　judgment　he　desisted　zealously　turning　to　the　alternative
  propositionthe　assault　on　Petersburgfor　more　significant　results。
  This　was　the　only　occasion　during　the　war　in　which　I　was　associated
  with　Hancock　in　campaign。　　Up　till　then　we　had　seldom　met；　and　that
  was　the　first　opportunity　I　had　to　observe　his　quick　apprehension；
  his　physical　courage；　and　the　soldierly　personality　which　had　long
  before　established　his　high　reputation。
  On　the　1st　of　August；　two　days　after　the　mine　explosion；　I　was。
  relieved　from　the　personal　command　of　the　Cavalry　Corps；　and　ordered
  to　the　Shenandoah　Valley；　where　at　a　later　date　Torbert's　and
  Wilson's　divisions　joined　me。　　Practically；　after　I　went　to　the
  valley；　my　command　of　the　Cavalry　Corps　became　supervisory　merely。
  During　the　period　of　my　immediate　control　of　the　corps；　I　tried　to
  carry　into　effect；　as　far　as　possible；　the　views　I　had　advanced
  before　and　during　the　opening　of　the　Wilderness　campaign；　i。e。；　〃that
  our　cavalry　ought　to　fight　the　enemy's　cavalry；　and　our　infantry　the
  enemy's　infantry〃；　for　there　was　great　danger　of　breaking　the　spirit
  of　the　corps　if　it　was　to　be　pitted　against　the　enemy's　compact
  masses　of　foot…troops　posted　behind　intrenchments；　and　unless　there
  was　some　adequate　tactical　or　strategical　advantage　to　be　gained；
  such　a　use　of　it　would　not　be　justified。　　Immediately　succeeding　the
  battles　of　the　Wilderness；　opportunity　offered　to　put　this　plan　into
  execution　to　some　extent；　and　from　that　time　forwardfrom　the　battle
  of　Yellow　Tavernour　success　was　almost　continuous；　resulting
  finally；　before　the　close　of　the　war；　in　the　nearly　total
  annihilation　of　the　enemy's　cavalry。
  The　constant　activity　of　the　corps　from　May　5　till　August　1　gave
  little　opportunity　for　the　various　division　and　brigade　commanders　to
  record　its　work　in　detail；　so　there　exists　but　meagre　accounts　of　the
  numerous　skirmishes　and　graver　conflicts　in　which；　in　addition　to　the
  fights　mentioned　in　this　narrative；　it　engaged。　　A　detailed　history
  of　its　performances　is　not　within　the　province　of　a　work　of　this
  nature；　but　in　review；　it　can　be　said；　without　trespassing　on　the
  reader's　time；　that　the　Cavalry　Corps　led　the　advance　of　the　Army　of
  the　Potomac　into　the　Wilderness　in　the　memor
