Dhameystir weedhan soo socota: Bishii Janaayo 27, 1863, Bateriga waxaa loo wareejiyay Grand Gulf, Mississippi, isagoo ku biiray difaaca Webiga Weyn ee Madow. Intii ay ku sugneyd Grand Gulf, baytariga wuxuu ka qeyb qaatay dhowr dagaal oo yar yar oo ay la galeen doomaha dagaalka ee Midowga, in kasta oo qaar ka mid ah qoryaha ay soo sheegeen caajis. Bartamihii bishii Maarso, baytariga ayaa ilaalinayay meel loo yaqaan Winkler's Bluff oo ku taal Webiga Weyn ee Madow, iyada oo amarro la siiyay in aan doomo loo oggolaan karin inay ka gudbaan barta. Bishii Abriil 29-keedii, maraakiibta ciidamada badda ee Midowga oo uu hogaaminayay Admiral David Dixon Porter ayaa duqeeyay saldhigga Confederate ee Grand Gulf, taasoo keentay in
Dagaalkii Grand Gulf, inkastoo Landis Battery uusan qeyb ka aheyn safka hore ee Confederate. Hal qalcadood ayaa ka adkaaday, sidaa darteed Grant wuxuu 24,000 oo nin ka soo dejiyay wabiga Bruinsburg. Nimankan ayaa dhawaan u dhaqaaqay dhanka bari ee webiga, iyagoo hogaaminaya Brigadier General John S. Bowen, oo ah taliyaha Confederate ee Grand Gulf, si uu u diro ciidan xannibaadda Port Gibson isku day ah in la joojiyo duulaankii Grant. Subaxnimadii 1-dii Maajo, laba gantaal oo Landis Battery ah iyo shaqaalahooda ayaa loo diray inay ku biiraan ciidanka xannibaadda. Intii lagu guda jiray Dagaalkii Port Gibson, baytariga ayaa toogtay rag ka tirsan ciidanka Midowga ee Major General John McClernand waxayna ku lug lahaayeen dagaal hubaysan oo ay la galeen 8th Michigan Light Artillery; cutubku wuxuu la kulmay seddex khasaaro ah intii lagu jiray dagaalka mana uusan kala bixin ilaa galabtii dambe. Hal mar oo dagaalka ka mid ah, baytariga waxaa sidoo kale lagu soo bandhigay rasaas hubaysan oo ka tirsan Ururka, ka hor inta aan la kala eryin weerarayaashooda. In kasta oo markii hore la qabtay, cadaadiska Midowga ayaa ugu dambeyntii ku riixay midigta Bowen, taasoo keentay in isbaheysiga ay dib u laabtaan ka hor inta Grant uusan ka badin. Kadib Port Gibson, Confederates waxaa lagu qasbay inay ka tanaasulaan booskooda Grand Gulf bishii Meey 3; Batariga Landis ayaa mar kale u adeegay qeyb ka mid ah ilaalada dambe.
